Vamos (check Laura’s review here) has a pretty solid deal from now through February 29: Two hours of all-you-can-eat tacos and all-you-can-drink frozen margaritas for only $26, Sunday-Thursday nights from 6-11 pm! Usually their Monday night deal is all-you-can-eat tacos + one margarita, so for $7 more you can imbibe to your liking, 5 nights a week. Bottoms up!
