Genna's really is as good as it gets.
It's cool without trying to be cool. It's part townie bar, part politico meet up, part hip kids hang out. It's quirky without being cliche. It's low-key without being dive-y.
Genna's has the cheapest and best happy hour in town. There's free chips and salsa, meatballs, etc. The drinks are 40% off during happy hour. It's a great way to kick off your evening.
Genna's has a great outdoor patio that fits about 50+ people. It's great during the summer.
The staff... They are always entertaining and very friendly. They make really good drinks. Try a sidecar. :)
Genna's used to have one of the better jukeboxes in town. Once in a while they'd have a DJ upstairs. There's not really room to dance, but it's usually good music.
Genna's really is the best bar in Madison.
