I like the Joyce as they do everything they can to stay true to the authentic Irish concept. Some of the decorations and chairs are straight from Ireland, the pub grub is all a spin on more traditional Irish fare, they've got a few Irish beers on tap and it's not unusual to spy a celtic band playing for the crowd. They do what they do well, but as Calgary's foremost Irish pub, the Joyce also charges a bit of a premium.
I love their appetizers here - the potato nachos are hilarious and delicious, and the Strawberry Brie dish is to die for. The beers on tap are very good, as is most of the food. It is a great place to stop by for lunch, or to grab a pint with friends.
The atmosphere is pretty joyfully Irish, and I like that.
