I've been going to the Old Fashioned almost weekly for the last two years or so. The combination of Double Bubble (2-for-1 taps & rails) and karaoke is a lethal one - Wednesday is the new Friday.
Great service, amazing food (No. 33 is my standby, and the cheese curds are generally regarded as the best in town), and an inviting, cozy atmosphere.
The only downside is they're often packed (even with the new expansion), but you can always enjoy the unofficial state drink and namesake while you wait.
