From her place of honor on the wall, Our Lady of Guadalupe has her eye on everyone who enters this bright storefront -- and we think she likes what she sees coming out as well. Taquería Pérez makes the most wonderful tacos in town: flat, round, soft corn tortillas are mounted with meats that tickle your tastebuds. Look up when you get to the order window: The posted menu explains the options -- lengua is tongue, carefully diced and pepper-rubbed; cesos is brain; tripas is tripe, barbacoa is "bar-b-que," spicy and melt-in-your-mouth tender. What the menu doesn't tell you is that each version -- you get four for five bucks, lettuce, tomato, onion and cilantro included -- is something special. We dare you to eat just one.
