I had a good experience at Duff's. I was there on Tuesday night (which is their wing night - 10 wings for $7.25 with the purchase of a drink which is roughly 3 dollars cheaper than the regular price). I ordered the wings medium. They were hotter than most medium sauces I have had but they were large and meaty and came cooked well done/crispy, just as I had requested. I also ordered the zucchini appetizer (breaded and deep fried zucchini with a dill sauce) which was decent but rather oily). My dining companion ordered the Caesar chicken wrap which came with uninspired fries.
I would go back for the wings.
