If you know what good meat tastes like, and want it in your burger, come to big boys! This place doesnt have your crappy wimpys/hero burger, with flimsy loose meat. When they promise an 8oz burger, you GET an 8oz burger. When you ask for some mix and match of ingredients that's not offered, they'll do it, no complaints.
By far the best burgers I've had in all of GTA, and I've tried quite a large number.
P.S. Try the big boy's poutine and replace the burger they put in it with their souvlaki, for when you're already eating a burger.
