Green Street is a small and cozy neighborhood bar whose excellent cocktails belie its unassuming appearance. The cocktail list here will impress you when the bartender or waiter hands it to you. What you don't know is that is just a small portion of the actual cocktail list: Ask for the book, and prepare to be amazed.
The cocktails are indeed very good. I particularly like the tiki-inspired drinks but you simply can't go wrong with a mixed drink. There are also small but well-edited wine and beer selections.
The food is just ok, in my opinion. There isn't a lot of selection between the $10-20 range; it's hard to order if you want a snack but not a full-on meal. The macaroni and cheese is good, and I've really enjoyed the seasonal salad with squash and quinoa (fall/winter), but in general I prefer to drink at Green Street and drink elsewhere.
In cold-weather months, Green Street gets bonus points for being small and cozy.
