I eat here from time to time. The service in the bar area is slow. In the restaurant, they have runners with the food, but if there is a problem, you need to tell the wait staff. the runners will just look at you or ignore you. The food here is good. I like the deep dish pizzas and the brewed root beer is excellent! It comes in a cold glass without ice. Also, try the Asian Chopped Salad or the Lunch specials - salad with half a sandwich and fries. It is a good price, and with a drink it is all about $10.
The atmosphere is professional, but not friendly or "warm". Every time that I have entered, I feel as though I am bothering the front staff. They always seem distracted. Sometimes they ask for the rewards card, and sometimes they do not.
I go for the food, not for the service. Of the many times that I have been there, only a couple of the servers have been good. Some are slow, and some are annoying - calling me sweetheart/baby/darling, or just not responding. Once they get the wait staff properly trained to serve, it will be an awesome experience!
