Considering that Monk's is a chain, the food is actually pretty good. Atmosphere and huge menu are chain-ish, but fine. (Can you tell I don't like chains much?!) Our server was friendly, professional and attentive.
The tator tots were perfectly cooked -- crunchy on the outside and soft on the inside. The chicken wrap (yes, trying to order something somewhat healthy!) was tasty and light.
I doubt I'll go back unless I'm invited by someone else who wants to eat at Monk's. If you're in the Middleton area, though, and would like some bar food and sandwiches, you'll probably be pretty pleased if you go to Monk's.
