I went to Adega with a group of friends from across the country while we were all in town for a conference. The restaurant is located in a beautifully renovated office building and has great ambiance.
The food is +++. I ordered a glass of white wine, the fettucini ceci (sooooo good - would love to learn how to make this at home) and a chocolate nutella deliciousness for dessert. The pasta really was amazing. Pesto, small bits of orange, what tasted like homemade pasta, cherry tomatoes and chickpeas. Really really good.
What I didn't like: The service was super-slow to get underway. I think they thought we were waiting on one more person, but no one checked to be sure. What I really didn't like was that a few people at our table ordered apps for the table - which I had a bite of, because I didn't really want them. Yet our server, in an effort to be nice to travelers, put the two appetizers on the two lowest bills. WHAT?!?!?! So I paid for an app I didn't want and didn't order. Not cool and not so easy to say anything about it. And I wasn't on an expense report (the stated reason he split it up that way) - I was on per diem. I would have been ok if the total cost of the apps had been split among all of the dining guests.
Other than that (which obviously still rubs me the wrong way), it was an excellent dining experience and I recommend giving it a try.
BTW - the restaurant is tucked away inside the lobby of a boutique hotel which is inside a converted office building. It can be tough to find, but look for a GORGEOUS converted bank building (Heinman's) and it's right next door.
