Pinstripes Oak Brook
How was it? Meh. The place seems designed like an office building. The food? It was ok. The staff was very helpful and attentive. But...I don't think I'll need to go back.
The place is HUGE, though and they have basically the same floorplan on the first floor as they do on the second. That whole second floor is for corporate events and private parties. So, perhaps they're going to do gangbuster business in private events?
