Atasca, which means ?neighborhood place,? serves authentic traditional Portuguese food in an elegant upscale setting. With its ultra-modern wall-to-wall glass facade, Atasca fits right into Kendall?s Tech Square. But inside, its like a regal Portuguese palace with colorful native ceramics, traditional folk paintings, and a brick hearth. And the food, which features authentic regional specialties, is out of this world. Start with the delicious small plates like the linguica pork sausage with grilled pineapple, the grilled fresh sardines in vinaigrette, or shrimp with a hot spicy piri-piri sauce. Main course favorites include grilled dry salt cod drizzled with hot olive oil and garlic; and south Portugal?s signature dish of succulent pork loin with clams, paprika, and cilantro. Though the food is always impeccable, the service can sometimes be prickly. Even if you are starving, waiters refuse to bring you bread until after you order; and they are very inflexible about splitting bills on different credit cards. But that aside, Atasca is the best place in Boston for authentic upscale Portuguese cuisine.
