Antonio Chi Su, also identified in Mexican media as Antonio Chi-Xuo, was a restaurateur best known publicly as the longtime husband of Mexican actress, dancer and vedette Lyn May. He was associated with the Siete Mares restaurant business in Mexico City and remained May’s partner until his death in 2008 following prostate cancer.
Much of what is known about Antonio comes from May’s later interviews and Mexican entertainment reporting rather than from an extensive independent public record. That distinction matters because modern biography sites have attached specific claims about his birth year, wealth, family background and business achievements that have not been reliably established.
Key takeaways
- Antonio Chi Su and Antonio Chi-Xuo are two spellings used for Lyn May’s late husband.
- He worked as a restaurateur and was associated with the Siete Mares restaurant business in Mexico City.
- May described their relationship as lasting roughly 25 years and said he was the only husband she married both in church and under civil law.
- Antonio died in 2008 after prostate cancer.
- His exact birth date, age, education, children with May and personal net worth have not been reliably established.

Who was Antonio Chi Su?
Antonio was a restaurant businessman whose public identity became closely tied to his marriage to Lyn May. An older El Sur account identifies Antonio Chi Su as May’s husband and the proprietor of Siete Mares, while later outlets including Univision and Milenio generally use the spelling Antonio Chi-Xuo.
There is no sufficiently authoritative civil or business document in the established record confirming which romanization was his formal legal name. The two versions therefore should be understood as reporting variants referring to the same man rather than as evidence of two different people.
Unlike May, Antonio did not build a career in entertainment. His public profile was largely connected to the restaurant business, and contemporary or near-contemporary documentation about his early life is sparse. Claims about a specific birth year, childhood, schooling or family background should consequently be treated with caution.
His restaurant career and Siete Mares
The clearest independent information about Antonio’s career places him in the restaurant industry in Mexico City. El Sur described him as the proprietor of Siete Mares, while Univision’s later account and other entertainment coverage have referred to Siete Mares as a restaurant chain.
The difference is worth preserving. The evidence supports describing Antonio as a restaurateur associated with Siete Mares, but it does not establish how many locations the business had, what percentage he owned, its revenue or its valuation.
Some later English-language biographies go much further, describing Antonio as a culinary innovator, cultural figure or mentor to other chefs. Those descriptions are not supported by the stronger material available about him. The documented picture is simpler: he was a restaurant businessman whose work was centered on Siete Mares.
A precise address sometimes attributed to his restaurant also remains insufficiently documented. The older El Sur material connects the business with Mexico City’s Chinatown, but the commonly repeated claim that it operated specifically on Avenida Bucareli has not been established strongly enough to present as settled fact.
His marriage to Lyn May
Antonio’s relationship with Lyn May is the best-documented part of his personal life.
Later profiles place their meeting at approximately 1980. May subsequently described Antonio as one of the most important partners in her life and said they were together for roughly 25 years.
In a 2021 interview discussed by Milenio, May said Antonio was the only husband she married both through the church and under civil law. Her description helps distinguish this relationship from other romances and marriages associated with her public biography.
The exact wedding year is less certain. Some reporting gives 1988, while other accounts use 1989. Neither date aligns neatly with May’s approximate 25-year description if that statement is interpreted strictly as the duration of a legal marriage ending with Antonio’s death in 2008.
The safest conclusion is therefore that they had a long-term relationship and marriage beginning in the 1980s, without presenting either 1988 or 1989 as definitively established.
Their private family structure is also less clear than some online biographies suggest. May had two daughters from an earlier marriage, according to Unicable’s account of her relationships. Reliable evidence does not establish that Antonio and May had biological children together.
His illness and death
Antonio died in 2008 after suffering from prostate cancer.
May has discussed his illness in interviews, and established Spanish-language outlets consistently connect his death with prostate cancer. A later Milenio retrospective places his diagnosis in 2004, although that specific year is not supported by a publicly established medical record.
For that reason, the broad chronology is stronger than the finer details: Antonio became seriously ill with prostate cancer and died in 2008.
Some sources specify January 2008 as the month of his death, but no authoritative obituary or civil death record in the documented material confirms the exact date. Presenting the year alone avoids creating a false level of precision.
His age at death is likewise uncertain. Online biographies sometimes assign him a 1949 birth year and an age of 59, but those figures have not been tied to a reliable birth record or other authoritative documentation.
Why Lyn May’s story about Antonio attracted renewed attention
Antonio’s name returned to entertainment coverage years after his death because of May’s unusually candid descriptions of her grief.
During a 2021 appearance on El Minuto Que Cambió Mi Destino, May said she had Antonio’s body exhumed after his burial because she was unable to let him go. Milenio and Univision subsequently reported her account, including her statement that she slept beside his remains.
The crucial distinction is that May’s statement is documented; the underlying event has not been independently verified through cemetery, legal or other official records.
She revisited the story in 2025 during an appearance on Experiencias Perturbadoras. In reporting on that interview, El Universal said May claimed the exhumation occurred shortly after the burial and that she kept Antonio’s body with her for several days before cremation.
Those details should be understood specifically as May’s account of what happened, rather than as independently established facts.
The story has inevitably become one of the most frequently repeated parts of Antonio’s online biography. Yet it represents an episode after his death, not the whole of his life. His documented identity remains that of a restaurateur, businessman and longtime spouse of Lyn May.
What is not publicly confirmed about Antonio
The limited nature of Antonio’s public record has created space for unsupported biography details to spread online.
His exact date of birth and age have not been reliably established. Although a 1949 birth year is commonly repeated, no sufficiently authoritative evidence supports it.
His birthplace, education, parents and siblings also remain undocumented in the reliable record used for his biography.
Descriptions of him as specifically Chinese, Chinese-Mexican or Mexican-Chinese appear in entertainment coverage, but reliable documentation establishing his birthplace, citizenship or exact heritage has not surfaced. It is therefore safer not to turn those descriptions into definitive biographical facts.
There is also no credible basis for a precise Antonio Chi Su net worth. Restaurant ownership by itself does not reveal a person’s wealth, and no financial filings, estate records or independently documented assets establish a dollar figure. Estimates circulating online should not be treated as verified personal fortune.
Similarly, there is no strong evidence supporting claims that he became a major community leader, pioneered a particular form of Chinese-Mexican cuisine or built a documented public legacy as a mentor to chefs.
Why his biography remains closely connected to Lyn May
Antonio’s public record is unusual because the person most responsible for preserving his story is his surviving spouse.
May’s interviews provide first-hand testimony about their marriage, his illness and the depth of her reaction to his death. They are therefore important evidence for understanding their relationship. At the same time, her recollections cannot substitute for civil records, financial documents or independent confirmation when the question concerns exact dates, ownership arrangements or other factual details outside her personal experience.
This explains why Antonio’s biography is both recognizable and incomplete. His identity as May’s husband, his restaurant career, his association with Siete Mares and his death in 2008 are comparatively well established. Many of the finer details commonly presented in modern online profiles are not.
As of August 22, 2026, his continuing public relevance comes primarily from renewed interest in May’s interviews and the extraordinary story she has told about grieving for him, rather than from newly discovered information about his business career or family history.
Frequently asked questions
Is Antonio Chi Su the same person as Antonio Chi-Xuo?
Yes. Established coverage uses both Antonio Chi Su and Antonio Chi-Xuo for Lyn May’s late husband. No authoritative record in the documented material establishes which spelling was his formal legal romanization.
What did Antonio Chi Su do for a living?
He was a restaurateur and businessman associated with Siete Mares in Mexico City. Some outlets describe Siete Mares as a chain, while older reporting refers to him as proprietor of the restaurant.
When did Antonio Chi Su and Lyn May marry?
The exact year is disputed. Sources variously report 1988 and 1989, while May has described their relationship as lasting about 25 years. Neither wedding year should be presented as definitively established.
How did Antonio Chi Su die?
Antonio died in 2008 after prostate cancer. A 2004 diagnosis has been reported, but the exact medical chronology is not independently documented.
Did Antonio Chi Su and Lyn May have children?
There is no reliable evidence establishing that they had biological children together. May’s two older daughters have been identified in reporting as children from an earlier marriage.
What was Antonio Chi Su’s net worth?
There is no credible, independently documented net-worth figure for Antonio. Specific dollar estimates circulating online are unsupported by reliable financial evidence.
Did Lyn May really have Antonio’s body exhumed?
Lyn May has repeatedly said that she did, including in interviews discussed publicly in 2021 and 2025. Her statement is documented, but the exhumation itself has not been independently confirmed through official records.
Conclusion
Antonio Chi Su occupies a relatively small but distinct place in the public record. He was a Mexico City restaurateur associated with Siete Mares and the longtime husband of Lyn May, who continued speaking about their relationship long after his death from prostate cancer in 2008.
His story is clearest when it remains within what can actually be supported. The marriage, restaurant career and death are well established; his exact birth details, wealth, family background and several grander claims about his business legacy are not. That more limited account is also the more reliable biography of the man remembered as Antonio Chi Su, or Antonio Chi-Xuo.
