I've been to Puck'n Wings a few times and I've had mostly great experiences. I love that there are many tvs, a real sports bar. It attracts hardcore game watchers including some solo eaters at the bar. We like the wing flavors, which range from 1-5 in hotness, the hotter ones 4 & 5 are decently hot compared to most places hot wings we've had in the area (which isn't saying much if you're into super hot foods) They're hotter than the wings at Crown & Dragon and hotter than Superhot at Duffs.
I don't think Puck'n Wings deserves the top spots on all of the hot wing recognition lists I've seen around the internet and papers but they're a decent wing for what I've tried in Toronto, and possibly the best in the Annex.
