Went to Duff's yesterday on a wing-whim. Ordered the combo 1 (20 wings, large fries, celery and dipping sauce, small pitcher of pop) for $24.
I ordered my wings medium hot (which Duff's proclaim "very hot") and hubby wussed out and ordered the medium mild (which would equate, again in Duff's standards) to medium.
Good, large, meaty wings arrived. Just don't inhale as you bring them to your mouth or the sheer overpowering vinegar will send you in to a coughing fit. The wings were tasty enough, but VERY vinegary. I THINK that the wings were hot spice-wise, but I couldn't be sure because of all the vinegar. Not sure if I'd go back for the wings.
Fries were out-of-the-fryer hot and crisp. A large is actually a large salad bowls worth...way too much for two people with hearty appetites. The dill sauce and blue cheese sauce was a nice accompaniment for the very crisp and fresh celery served. Pop pitcher was quite small, only yielding two drinks.
The service was awesome. Very attentive, and helpful.
That being said, not quite sure I'd return. Wouldn't take much twisting of the arms if a group wanted to go there though, so it wasn't too bad.
Also, it was a Monday and the place was heaving. Despite that, there were plenty of servers and a nice "busy" atmosphere.
