I liked Duffy's. The food portions were huge. Not a fan of the wings though. I may recall incorrectly (it has been a while0 but I think their wings had more of a cayenne pepper type taste to them than a true buffalo sauce. Not a fan of that type sauce. Perhaps offering at least a small variety of sauces (the current one, buffalo, teriyaki) would be a good marketing decision. The fish and chips sound like a good idea, malt vinegar for the fish is a must!
