In my opinion this is the best place in Madison to see live music.
The sound is always amazing. I dont know what they do but the quality of the audio here is stellar. They always have a decent act several times a week and it has never been too crowded.
2 bars going during most shows makes it easy to get a drink and they have a great selection at good prices.
Their happy hour is buy one get one on taps and rail cocktails which might be the best in the city. Pair that with the patio in the summer and you have an amazing place you have to visit!
