WIthout a doubt, my favorite restaurant in Madison. It's always packed, so be prepared to wait.
I've never had a bad meal or cocktail here. Their cheese curds are the best I've had in Madison (and yes, they blow Old Fashioned out of the water). Bibimbap is amazing. Chicken and waffles is the best I've had.
The ambiance is really great and there are windows everywhere so you can people-watch or whatever. Staff is generally very friendly. Overall, not a single bad thing to say about this place.
