We had a great time at Madison On Tap. The sheer variety of beers was amazing. No way anyone could taste them all. I loved all the stouts and porters especially the Dragons' Milk, but my favorite beverage was the Lombardi Limonita. Tasted like the lemonade I loved as a kid but with a kick.
I also really enjoyed the band and the various games that were available. Really my only complaint would be the lines for the restrooms. Even with the addition of some porta-potties, the lines were really long.
