The best place in Calgary to find a diverse tap list of original craft beers. Yes, they have fewer taps than some of the numerous beer bars locally, but they will always have things you have not tried and actually want to try. Other than the 2 Brewsters beers that are always available, each keg is the only one of that beer they have in stock, so visiting twice in 2 weeks will often give you an entirely new list of brews to taste. I had my first Mikkeller here; I never see them on tap anywhere else in town. Even when I am familiar with the featured breweries, the choices will often be brand new or limited edition beers I haven't yet tried.
Short menu of pretty good food; pizza can be made gluten free and they are usually willing to remove a topping or two if you have special preferences (for example, vegetarian). They've made me a pizza with two different halves more than once. Also, surprisingly good cheese board for a beer bar! The green pepper Madagascar is worth trying at least once.
Accessible if you enter through Brewsters on 11th Ave. Enough low tables mixed in with the high ones so that people in wheelchairs should be able to find a place to sit with others. I haven't tried the accessible washroom, but the door looks heavy.
