I would use profanity to describe my first encounter with this place, but instead, I will tell you that thanks to their poor service, we had a great dinner at the Passport restaurant across the street.
The second time, I went there we had decent food, but the atmosphere was so crowded and noisy that we didn't really talk much, as we were with friends from DC that I get to see 1-2 times per year, that was not acceptable.
The third time was with a corporate function for my wife's company. Food OK, drinks OK. Were it not for the party room and having access to our own wait staff and a pre-arranged menu, I am sure that we would have had the same cruddy service the Upstream is renown for.
Add to the cruddy service, their uninspired "craft beers", and you get a great place for young 20 somethings to act pretentious, but there are a lot of better places for dinner near by.
