We here at the City Paper love cultural holidays. Chinese New Year. St. Patrick’s Day. And now Cinco de Mayo. It’s fun to take a day and appreciate a different set of customs and traditions, and to commemorate Mexico’s win over the French at the Battle of Puebla. And if tequila happens to be involved, well, that’s just a lucky coincidence. One of the best Cinco de Mayo celebrations around town (and there are many of them, like at the Tattooed Moose and Big John’s) is sponsored by the City of Charleston and held in the Visitor Center Bus Shed. You can dance to Orquesta GarDel, Taton Y Tremendo, and DJ Luigi or watch the professionals — Buen Ache and Estilo 6 — do it for you. Some proceeds will benefit the Ryan White HIV Care Program at Roper St. Francis. Don’t forget to bring some money for the Mexican food and drinks. It’s not Cinco de Mayo without a margarita.
