Staff is excellent but something happened to the wings.  I ordered my usual - hot and x-tra crispy and the wings were pretty nasty this time around.  They were the type of jumbo wings that I have never had before at zipps and they were anything but xtra crispy - skin was rubbery and well, blech.  I was totally disappointed and I don't know if I will be able to order them again.  I have had them numerous times before and they were really good, not today though.
