I will be making a trip to San Antonio tomorrow, and I was hoping to get a recommendation from some Austinites about a place to eat. I will be at the Coliseum Complex on E. Houston St. (pretty close to the Alamo), and I will have a car. If you had one afternoon in SA, where would you eat, and what would you get? I have searched the boards, and have found some recommendations and reviews, but most give a list of 5 or 6 places. I'm leaning toward Tex-Mex/Mexican in whatever form, but am open to anything. Extra points for good margaritas. Any ideas?
Edit: I placed this on the Austin board since that is the board I follow, and I know most of the people there, but it has been moved to the Texas board. I'm certainly willing to accept recommendations from anybody.
