I went to this place a few months ago when it had just opened. It definitely seemed like a work in progress, but given the high traffic location I was under the impression some good things might develop, even though the name is quite daft.
Went back the other night and not much has changed -- lots of exposed wiring, random metal things sticking out of the wall, dodgy sound system and an overall "we're renovating" vibe. There's a lot of potential with the space but it looks like there's no plans to dress things up a little. Even the bar looks like a temporary set-up with Pabst Blue Ribbon taps taking up the majority of space. PBR also appears to be the only draft available.
Still, the beer is cheap: $5-something for a PBR served in a mason jar. Mind you if you don't like PBR (which is not a very good beer) then you might be out of luck. Pitchers are $13-something which doesn't really seem that cheap to me given the low-quality selection.
I think Jang Bang has potential down the road, but I was a little disheartened to see that very little has been done to improve on the space since I last checked it out months ago. The corner of College and Bathurst is a damn zoo on weekends so take advantage! As of now its makeshift appearance doesn't make me want to drink there, let alone eat.
