We ate at the rooftop last week and the experience was very nice. Be prepared to wait around 30-45 mins if you want to have a table there, as there is quite a queue. The staff is extremely kind and helpful, the service reasonably fast. The foot is good, but not particularly memorable (as others seem to have noticed too). If you want memorable food, go elsewhere (Corndance Tavern in Mishawaka, for instance). Overall a pleasant experience anyway. Wouldn't come back if not probably for the location and the rooftop.
