Then there's the physics graduate lounge. I kindda like the idea of having blackboards for discussions.
My lunch carts. I couldn't survive without them! Great source of food.
One of my favorite haunts: the medical library. Though it's pretty far off, it's one of the most splendid places to study in. It's like studying in a museum, exhilarating feeling at first, but wears off after you found out you still can't solve that bloody assignment problem. They even have exhibits on display... On retrospect, it kindda looks like the library I saw in Prague.
