I can say from a LOT of experience I have never had a non-crispy wing from Duffs. Of course, I order them Extra Crispy wherever I go. I like Duffs sauce and their fearlessness when it comes to Extra Hot (or whatever they call their stupid-hot wings these days). They aren't the best wings I have ever had, but they have always been far better than Anchor Bar, IMO. La Nova is average in everything they make, IMO. Average wings and slightly below average pizza.
Some think they put too much sauce on the wings. I get that. But if you just want less sauce, order them that way. It isn't hard to order things the way you want them. If the place doesn't fulfill your special request, then you have a complaint.
Some of my favorite wing places are no longer around. Tally Ho in Niagara Falls may have made my all-time favorite wings. They have been gone for years. Rudy's on Millersport Highway was a fantastic place for many years, too. RIP Rudy's.
I think Mister Dee's on Beach Road in Cheektowaga makes some of the best wings and beef-on-wecks and fish frys in the world. Maybe not THE best, but damn close. And they are consistent. The rest of the food on the menu is very good, too.
