I travel to Calgary every few months, one of the *MUST* stops is here. The meat pies, with the hot sauce and the lemon juice.... get an ice tea or something with a bit of sugar in it to cut the heat later.
The place may look like nothing fancy, but the place does a hopping business. Sit there for an hour, eating your two meat pies, trust me, come with a big appetite and enjoy two with a friend.
