Literally any bar/tavern in Buffalo will make great wings. It's not, after all, rocket science.
The Amherst Ale House on North French Road has amazing wings. They have Crown Royal wings, which are covered in a Crown Royal BBQ sauce and then grilled after being sauced. They won "best wings" at a Pizzafest a few years ago. The restaurant is located outside of Buffalo, in Amherst, but it's worth the drive if you're looking for good wings. We prefer those, though it's hard to find a bad wing place here. Locals usually just order from whatever pizzeria is close to them- we don't often go out of our way to find good wings because we don't have to. :) If you do go to the Amherst Ale House, try the stuffed banana pepper pizza. It's awesome if you love spicy food.
