Cecilia Cuellar would not give us her phone number, address or any way to get in touch with her, so if you're looking for the best tamales in Houston, it might take a little detective work. If you have patience, though, all you really have to do is drink a beer at The Harp (1625 Richmond) and wait. Chances are decent, if it's a weekday night, that Cuellar will wind her way through the bar with a small child in tow, offering her homemade tamales. "She does come by, but on different days. It's not consistent, but it's at least once a week," says Deck at The Harp. He guesses that she lives in the area and visits several neighborhood bars. At just $6 a dozen, the tamales come in beef, chicken, pork and spinach-and-cheese. (She won't let you mix and match your dozen, though.) And the green salsa that comes with it is perfecto. So get out on that bar stool, have a drink, and while you're waiting, make a toast to Cuellar.
