here's the break down in the loyal one's view:
anchor bar- great tasting SAUCES. they also get points for the history of the place. i've found their wings to be small and on the greasy side.
duff's- gets points for having a better atmosphere and being around the corner from my house . only problems i've had with duff's is that their hottest isnt very hot to me, and alot of the time, their wings are swimming in sauce.
if a winner is being chosen between these two, it's duff's for sure.
now, if i was asked who has the best wings in wny, it's BAR BILL in east aurora. their wings are always a good size, they have great flavors(hot & spicy bbq is awesome), and the wings are ALWAYS cooked perfectly.
