La Guerrerense
Fans of Baja-style seafood flock to this bustling counter inside the Parián Condesa food hall for fresh, delicious crab tostadas, caracol (sea snail) ceviche, oysters and clams on the half shell, and shrimp and octopus cocktails. Enjoy your food at one of the casual tables, imagining you're at the beach in Ensenada, where the original La Guerrerense (which was much lauded by Anthony Bourdain) is located.
