A great place to enjoy a drink, and an incredible beer selection. I would recommend a Delirium Tremens or the Bells Hopslam. They have a huge selection of beer on tap, as well as bottled beer. The bartenders there are really nice, personable and knowledgeable. This is the bar I went to at midnight on my 21st, and the bartender was super nice and poured my whiskey extra strong because it was my birthday.
The atmosphere is really cool, lots of exposed wood, and glass top tables with random bits of memorabilia underneath. The lighting is what it should be for a pub and the overall vibe is very chill. The one complaint I have is that their clientele is sometimes a little snobby and high-strung. A lot of grad students hang out here and think of it as their bar, so they get a little uppity when undergrads show up. But if you can ignore the snobs, it's a great place to sit and have a drink with some friends in a relaxing and chill atmosphere.
