I wasn't overly impressed with the cafeteria-gourmet vibe in South Street. You pay restaurant prices for a quick burger in a bag and some pretty good fries. There are tons of great toppings to put on your burger, and the burgers themselves are pretty good, though the one I had was a little dry after taking it home.
The poutine looks pretty good, but I can't justify the extra thousand calories on an already leaden meal. Service is quick, burgers are expertly assembled like ducks in a row.
I'm just pretty ambivalent about the burgers... it was a better burger than most fast-food joints but not worth the price.
