I love Duff's. I really do. I don't think I've ever been disappointed with a meal there. Wings are deep fried, they will be greasy. Once you come to terms with that, you will have a tasty experience.
Our orders never vary. We always get the deep fried pickles (might even be the best in the city), potato wedges (SO GOOD!) and of course wings. I always order medium hot and my friends get Hot Honey Garlic (wusses). :)
Service is good and fast. Only problem we ever run into are the table runners wanting to clear our table before we're actually done.
