The Shack, as it's known to by locals, is probably the coolest dive in CB that isn't actually frightening to hang out at. It's got great bar food (the wings may be the best in the Omaha metro area) and the beer specials are great. It's ostensibly a sports bar, but the juke box usually has good music. Just be careful on the weekends. I've seen more than one fight break out at this place.
