The Piglet is a nice little bar in downtown Champaign. While the indoor part of the bar is very crowded (and there are places that are just as dark as it's big brother on Walnut), the outdoor garden is quite fantastic. Plus, I'm a big fan of all the brewing equipment in the windows.
Otherwise, there's not much to set the Piglet apart from the main brewery. The beer list is okay, but not otherworldly, and the spirits are also pretty limited. A good place if you're into beer, and if it's summertime.
