Despite being home grown I only went to Bar Bill about a year ago because East Aurora was always out of my way and Duffs, Anchor Bar, Gabriel's Gate and Goodbar were always closer.
The wings I had at Bar Bill were hands down the best of those. To be honest the best Anchor Bar wings I've had were at the airport
I am also finding that while I don't know if the best wings are in Buffalo, what you get at your average pizza place on the corner is in league with "the best in NJ"
