As other reviewers have said, this is a nice place to get a beer and chat with friends. It's relatively quiet compared to other places, and they do keep trivial pursuit cards around at the bar, which can add a little fun into the mix if you're the trivia type.
I struggle a little bit with the "gastropub" classification on this one, unless you call any bar & grille establishment a gastropub. I've never had food here that I was particularly fond of, nor would I consider it one of their selling points. It's merely ok.
Overall, The Map Room serves a different clientele and provides a niche atmosphere unlike the other establishments in the Square, which is why is still exists.
