The Guggenheim Museum Soho, located in an ornate brick building on the corner of Broadway and Prince St. isn't what someone visiting it for the first time might expect. Despite the famous name, the Guggenheim Soho is very small; the first floor has been completely taken over by stores, with the museum itself taking up only one floor of the building.
The gallery on the second floor is an open space with large windows letting in lots of sunlight. The interior design is in the same fancy style as the brick exterior, with a marble walled entrance, wood paneled elevators and gilded columns. Since admission is free, anyone can walk in off the street and not feel out of place or underdressed.
The permanent exhibit is Andy Warhol's series of paintings, The Last Supper. It's the type of modern art that's difficult for an ordinary person to appreciate, but a curious tourist would probably enjoy a quick hour or two visit.
