I never stayed in the hotel here, I just visit the bar RIGHT on the lake. It's like you're on vacation when you visit Edgewater's bar. There is no better place (beside the terrace at the student union) to enjoy a cold one in Madison.
Service is quick and friendly and they have Spotted Cow on tap :) Their food is pretty decent and the prices are just right. Try a bloody Mary, they give you Spotted Cow as a chaser and the mix is nice and spicy.
