I went to Tacos & Tequila last year when I was still new to the city, and it ended up being one of my favorite events I attended all year. First of all — tacos and tequila? That’s a very specific era of music, and if you know, you know. Tacos & Tequila goes down Saturday, April 11 at Sam Houston Race Park, and if last year was any indication, this is one you don’t want to miss.
