Had lunch at Tlaloc the other day. Once they gave me a hard time for shooting down on their restaurant from their balcony. But that was a while ago. It's ok Mexican food for downtown. A little pricey and I don't like the fact that they don't put prices on their menu board. Their salsa bar is pretty good though :) There's a Pancho Villa downtown but I don't really care for it. Every now and again I'll take a BART trip up to La Taqueria up at Mission and 25th (I think), which is hands down the best Mexican food in the SF Bay area.
