Went in for the opening special of their original 6oz burger, fries, and a can of pop (or water) for $5+tax. I liked it! Maybe because it slightly reminded me of Johnny's Burgers out in Scarborough - that old school no-frills burger taste, none of that fancy-schmancy stuff they're doing to burgers these days. If they served their burgers though at the same price as Burger Bar's burgers ($11.50, no sides) then I'd be giving less review stars.
I didn't find the staff to be rude (they even replaced the can of pop for water and didn't charge extra, places usually charge extra for that). The place does need some help with their decor though.
As long as they keep their prices at a decent price, I'd keep going back.
