I worked for local hotels for 10 years.  Guests would ask how to get to Anchor bar and we directed them to Duff's.  Their sauce is better and the wings are better quality.  I seriously want to lick the bowl of sauce when im done eating them.  Of course as long as the restaurant used Frank's Hot Sauce your'e in business thats what makes the wings so yummy.  Frank's and you have to cook the wings.  Sometimes they arent cooked all the way thru and are a little pink, that is gross.  Wings take longer than you might think.
