Taco Bell that you tried to hate on, has an even stronger case. You can't get out of a standard mexican restaurant under $15. (remember tips?) They have SEVEN of the best low cost meals I have ever had at fast food outlets.
Taco Bell is not Mexican food. It is Tex-Mex inspired junk food. That's not to say I don't enjoy it on occasion, especially a green buritto and a MexiMelt. But there are at least 30 good Mexican restaurants in Dallas I can go to for under $15 (food, non alcoholic drink, tax and tip), many under even $10. And there isn't a single meal at Taco Bell I would consider one of my favorite low cost meals. Del Taco just opened in Dallas, and I personally like it better.
