I came to visit this place with a friend when we stopped off in Pittsburgh. This is definitely the most gangsta building on any college campus I've been to so far. 6 stars for sure!
The architecture on both the exterior and interior of the building is unbelievable. We came on like a Tuesday and admission was free. The aura of the place hits you as soon as you walk in; it's like dammmnnnn. We hit up the nationality rooms, which were all very interesting. They have so many of them actually, so you could easily spend a good portion of the day here. You have to pay for the ones on the first floor for some odd reason, so we skipped those. We also took the elevator to the top floor, and there were some nice views from up there.
Great place to visit and I enjoyed it thoroughly. The entire surrounding area of the Pitt campus was pretty nice actually.
