I'm in Houston this week. We all know D.C. is not particularly known for its delicious Mexican food, so I've made it my goal to eat as much tasty Tex-Mex as possible while I'm in the Lone Star State. Any suggestions? What's the best hole-in-the-wall place for authentic and delicious cuisine? Who has the best fajitas? Where should I go for the most refreshing margaritas? Send me your suggestions, and I'll post the results of my research later this week.
