I like to check out local hbs whenever I'm in a new city so I checked this joint out. It was pretty small but they did pack a lot of good stuff into the space. They only carry wyeast for liquid yeast ( I'm a white labs Guy) not that Thats a bad thing , they do carry dry yeasts too... though they keep them on a shelf on the showroom floor ( not refrigerated). They had a few brews for tasting which was super Rad. The hop selection was very good, Lots of esoteric types. The staff there was great.... well it was great for me because they just let me roam around and didn't breath down my neck which I really dig. Less informed brewers may not like having to come to them for questions. When you're  new the veterans can seem a little intimidating.  All and all I would say check this joint out if your in Madison.  SUPPORT YOUR LOCAL HBS!
