My wife and I went to Gaslight even after reading the reviews below and our experience was a very positive one.
Plenty of parking in the neighborhood and the decor/setting was pretty cool. More NYC than Boston.
The service was attentive and friendly, if not polished.
We started with a fresh, warm, whole baguette and had the escargots, garlic and mussels soup and the haricots verts - all of which were very good.
We enjoyed the lamb and the braised pork (with lentils) as entrees and those were excellent.
We finished off with the molten chocolate cake, which was tasty enough to satisfy our sweet tooth but not so heavy as to bloat us.
I recommend Gaslight for those who are looking for a very good meal for reasonable prices.
