One of the few places I've been where the painfully subpar waitstaff attention is VASTLY outweighed by the ambiance, music, food/beer selection, price, incredible quality and overall enjoyability of the pub as a whole. It's like going to Monks... expect a wait, but expect it to be worth it. Especially if you order the brie/bleucheese/mushroom fondue, or the turkey/jalapeno reuben, or the steak/brie/onion/focaccia sandwich... And really, when you're in an atmosphere that rustic but urban, old school but trendy, with such fabulous adult alternative music, local and international beers, and food you could get addicted to, where's the harm in waiting a bit?
Pros: Food/Beer, Atmosphere/Music, Price
Cons: Promptness/service, first-come seating
