Hands down the best wings I've had in Toronto. They have tons of flavours to try, none of which have been awful, though some are definitely better than others. Personally, I suggest something from their hot and wet choice.
Unlike other wings bars, Fanzone serves their single orders as a fixed 10 jumbo wings rather than single one pound orders. Because the wings are jumbo you're definitely getting your money's worth on a regular order.
In terms of staff and atmosphere, I rate these guys the full 5 stars also. The owner/manager appears to be a very welcoming guy and the wait staff are always nice and prompt. The restaurant has a dozen televisions playing the big sporting event, with individual screens at the booths. Because the restaurant is unfortunately on the smaller side, seating can become difficult on big event nights and it gets loud at times with all the team spirit, not that the latter is a problem.
I highly recommend Fanzone for watching sporting events in groups or even just to hang out with friends over some wings.
