No, it's The Arches, the row of condos that look like Monopoly hotels. (to me, anyway). So when you're going up 22nd, they're on your left after you pass Arch.

SLA was catty-corner from this site (of The Arches and formerly the Electric Factory), on the southeast corner. They seem to have moved, though. I think they're at the main school district building on North Broad.
