Atasca is tucked away on one of the more quiet corners of Kendall Square, within easy walking distance of the subway. There's plenty of parking nearby too.
On a weeknight, it was nice a quiet in there. I had reservations but they weren't necessary. Our waiter was very attentive, almost too attentive, but brought out our wine and food as soon as it was ready.
The wine list is very good and reasonably priced, especially for Boston. There is a good variety of Portuguese and South American wines with many options by the glass. The waiter's recommendations were spot on.
We had the crab cakes and bean salad as appetizers and both were excellent. For dinner, my friend ordered the Caladeirada de Peixe (seasonal fish with roasted tomatoes and veggies) which was very good. I tried the grilled salted cod and it wasn't my liking. There was way too much oil on the plate, enough to coat everything too generously. That was the only negative of meal, though.
Desert was good with a huge portion that was too much for two people. They have a small selection of port and brandy that made for an approachable after-dinner drink.
All in all it was a positive experience.
