This is my - and everybody's! - favorite bar in Quebec City. They have an enormous selection of bottled beers, rotate many on tap, and list over 50 single-malt scotches. Beer is reasonable, while drinks are a tad pricey. Decor is very British-pub, dark wood and brass, but comfortable and warm. The atmosphere is laid back and the crowd tends to be younger - there's live music on most nights, and the house band (the Cape Breton Barbarians) plays folksy stuff that you don't have to scream to be heard over.
Some of the best pub food in town, but be prepared to pay a little more for it, and make sure you're in the mood for a crowd - it's usually packed. Service is friendly, if a bit harried.
Not to be missed - a quintessential Quebec City experience!
