I showed up here about 15mins before closing time, and got brusque but friendly service.
I went with a burger and a mushroom poutine. The burger was solid, and I would definitely go back and eat there again.
The menu has a ridiculous amount if toppings available to choose from, and so I don't remember exactly what I got. I've come to expect a large number of topping options here in North America, but even with high expectations this place killed it with the toppings.
The poutines have a decent selection of ingredients to choose from too, and I really rate their mushroom version. The gravy was thick and dark, which I'm a big fan of - if you've never tried a poutine in Quebec, ignore that last sentence and just know it's good.
The decor is 50's/60's burger joint (with lots of neon lighting), which is pretty par for the course these days (not bad, but not good).
Just remember there's no 'S' in the name of this place! I'd been thinking of going here for a month before I realised that it's "Chee"burger - what's with that?!
