I've now been to Kitchen 56 on two occasions and both times I was dissatisfied. I feel like this place could be so much more but just isn't. I agree with most reviews on here that the food wasn't bad but just nothing special at all, especially for the price. Unless you go during happy hour, which I do hear is good, things are very overpriced.
The staff is friendly enough but the service was terrible. On one occasion our entire table had nearly finished our entrees before one member of our group had received his food. Both times I have been the service from the wait staff and kitchen has been extremely slow, even when there is no one in the restaurant.
Unless you are going for happy hour, or just enjoy very mediocre restaurants, Skip it.
