Mark, I'd be very tempted to do a butcher shop but of course Roomie's Granddad and later her Uncle had a butcher shop in Aspinwall. 
Seriously though, that building is actually smaller than it looks and a butcher shop would fit in it without looking overcrowded. It could be pretty simple with a white meat case crossways about a third of the way back that would show up nicely through the front windows. A beef quarter hung behind the meat case to one side and a butcher-block to the other and you would have a believable scene. You could even get carried away and put up two walls in one back corner with a door and you'd have a walk-in cooler. Oh, and a ring of sausage hung. Can't forget that!
Heh. EDITED FOR CLARIFICATION. It's not that I get Mike and Mark mixed up as people but rather that my senior brain sometimes takes over the fingers on the keyboard.
