Glad there wasn't a line up when I went! Prob would've been disappointed if having to wait 30 minutes for it.
I've never had this in the states so I can't compare but for the price ... it doesn't seem to be worth it. There are many mom and pop shops in Toronto that make better gyros than here.
I got the combo platter (reg) and it came to be around $14 for it. The portion is decent but feels like something that should be $10.
It's definitely a good alternative to other quick bites in the area but I wouldn't come here just for the sake of eating it.
