This Latin and Caribbean tapas joint is one of the best date-night restaurants around. The place is stylish and sparkling, modern and romantic. And the food is great. One standout is the carne mechada, a Puerto Rican version of pot roast. The deeply flavored beef stew is served with gnocchi made from yuca, cloaked in brown butter and garnished with sage leaves. It’s a delicious fusion of bistro and Borinquen.
