For a festive dining option in the Seaport, head to Rosa Mexicano, an NYC import. There’s always a crowd, and colorful Mexican decor adds to the atmosphere. Staffers are friendly and willing to talk about the lengthy menu of Mexican favorites—flautas, tacos, enchiladas, plus exotic house specialties like crispy chicken breast stuffed with huitlacoche or grilled wild jumbo shrimp in a garlic vinaigrette. The guacamole, made tableside, is a must, as is the signature frozen pomegranate margarita. If the dining room is full, grab a seat at the bar for a cocktail and bar bites like tlayudas (Mexican pizzas) or share “Three Feet of Tacos” with friends.
