The best fish tacos in Mexico City are at El Pescadito. A beloved name to locals, this no frills locale serves up excellent tacos with an endless selection of different salsas and pickled onions, all washed down with beer. Their best taco is undeniably the quesotote– a chile relleno chopped up and served alongside crispy breaded shrimp, wrapped in a corn tortilla. Order, eat, and then pay!
