The Baja menu at this Southie spot emphasizes bright and summery tacos and inventive oyster dishes. Loco's fried fish taco has a tropical edge thanks to a topping of pineapple aioli, while oysters -- when not served cold over flavored ice -- are grilled over charcoal with red pepper butter and ash salsa. More than 40 tequilas and mezcals are available, either straight or in zesty cocktails like the wicked hot Little Devil.
