I always thought the "secret sauce" was just thousand Islands dressing with some relish mixed in.
Did realize I have one other original recipe. This probably won't mean much to many but back in Lancaster (NY) we used to have a pizza place named Vargos. Was the best pizza joint for miles... well, I have their sauce recipe. Only way to really use it is to break it Way down, its a bulk recipe.
Best wings I've ever had were at some crummy little bar at Broadway and Rt.77 out in Darien Center/Corfu. Place is long gone though.
