I've been to Cooper's a few times and it's one of those places that I want to like more than I actually do.
I'm certainly no beer expert, but I would say they have a pretty good selection of different beers from around the world (probably 30-40 in total).
I would rate the food as average to pretty good. I had a duck confit a pesto pizza which was very good. I've also had their duck confit mac and cheese which was just ok. They advertise a sandwich called the Broodwich as "the best sandwich you'll ever have", but it's really just a sandwich with a bunch of standard deli meats.
Overall, a good place to go if you're in the neighborhood, but it's not worth making a special trip.
