Did many dinner orders from here when I worked a block away. The real win at GBC is their homemade ice cream sandwiches. Great ice cream between two gourmet cookies. If only there was a way to warm up the cookies without melting the ice cream...
I think their complete menu is done really well. Burgers are good (not super-awesome, but solid). Onion rings and poutine is good. Shakes are great. They're pretty timely with orders, whether you do a large order for pick up or eat in. If you choose to eat there, they have a balcony from where you can people watch :).
Solid joint.
