In his book Taco USA: How Mexican Food Conquered America, award-winning ¡Ask a Mexican! columnist and author Gustavo Arellano combines cultural criticism and personal anecdotes to put an array of interrelated topics in a historical context. Spanning from Mexico's early gifts - including chocolate and vanilla - to worldwide cuisine to SA's own chili queens and Taco Bell's Doritos Locos Tacos, Arellano investigates our relationship to and appropriation of Mexican food. The first margarita machine, the burrito renaissance, salsa upstaging ketchup, and Jesus' appearance on a tortilla are serbed up in one big buffet without borders. On Wednesday, Arellano speaks and signs books in conjunction with UTSA Celebrates National Hispanic Heritage Month. Free; 6:30pm Wed, Sep 12; UTSA Downtown Campus, Buena Vista Building 1.326, 501 W César E. Chavez, (210) 458-4768, utsahispanicheritage.wordpress.com.
