Seafood is to mariscos as the Port of Houston is to Puerto Vallarta: You need seafood, but your liver and libido need mariscos. No joint in the city understands this better than Tampico, the perpetually packed, fluorescent-lit outpost of la vida loca on pockmarked Airline Drive. Here's the crazy concept: Supply fresh, locally caught shrimp and red snapper and let the patrons choose a fish straight off a bed of ice. Tampico is best with friends who will help you devour a whole snapper a la plancha -- a fish sizzling on a huge skillet, ideally accompanied with corn tortillas and fiery diablo sauce. Throw in some of the best margaritas, mojitos and pina coladas in the city, and suddenly you're on a completely different latitude, all for a price that won't crush the cartera.
