If you need something to do this weekend, check out the 57th Street Art fair (from Woodlawn headed several blocks east and going north to 56th Street) in Hyde Park. This is the kick off for the summer Art Fair Season and outdoor festival season as well. My mother started taking me to this art fair 30 years ago and very little about his changed since. Unlike just about every other local art fair it is in the middle of the residential neighborhood (since the Gold Coast Art Fair moved to Grant Park last year), and the center of it is the Ray School. Makes it real convienent for bathrooms.
Also the school yard makes a great makeshift food court and eating area for the local vendors and the food is not to be missed. Sure Robinson's is there with their standard BBQ but get the Chicken Devine, blooming onion or must have funnel cake from the locals. Also the parents from the Ray school sell pop still at a buck a can and there is some to die for roasted corn on the cob.
The food may not be art but it feeds your soul as the art feeds your intellect and eyes.
Also the local businesses within the Art Fair route remain open, including the legendary Medici's on 57th, a great lunch spot and dessert spot with open air eating. Also 57th Street books has your literary needs met as well and is open for business.
Not to mention this is the campus of the University of Chicago campus, so if you need a repreive from the crowds, just take Woodlawn south to Rockerfeller Chapel and you also have the caml Midway Pleisance at 60th Street. And on your way there is the famous Frank Lloyd Wright "Robie House", though tours are not free, still its something to see.
The Art Fair runs on Sunday from starting around 10 or so but be there in the early afternoon at the latest because artists start packing up and this neighborhood and Art Fair is not to be missed.
