Cool, small, (and I mean small!) unique, place. The menu consists of a boatload (aka good selection) of beers and wines written on the chalk board. This can make it a little difficult to figure out what you want at times, but the bartenders tend to know their stuff and can help you out with ordering. They color code the beer based on broad styles as well.
Anyway, when this place is gets going it can be a real ball, you'll get to know the people next to you (if you want), can play a bunch of random games such as battleship with your fellow bar goers, and order some light appetizers if you so please.
There's no other bars quite like the Whining Pig, definitely a place to check out at least once to experience for yourself.
