Chef Rick Bayless has two restaurants in the same building there. They're mexican themed with influences from cuisines all over the world. I can honestly say that I've never had a better meal in my life, and I've had some crazy fucking meals. Do a web/phone book/411 search for "the Frontera Grill," You WONT be dissapointed. (PS: They have the most extensive Tequila bar in the city, they have like 75 different bottles or something insane.)
