Though there are Tex-Mex restaurants all over Houston, Lupita's is one of those mom-and-pop-style family joints that inspire loyalty thanks to fresh ingredients, reasonable prices and tasty, consistent food. It starts with the complimentary chips served not just with a bowl of warm, roasted tomato salsa, but also with a side of smoky, addictive charro beans. Margaritas are large, strong and inexpensive. The beef fajitas are some of the best in the greater Houston area, and the flour tortillas are peerless. Soft and slightly chewy, they are Lupita's secret weapon: Twelve inches in diameter, the large, hand-pressed tortillas come to the table right after being cooked on the comal, and they never fail to impress.
