So.... a friend of mine says her brother's friend used to work there and this is how he said they prepared it:

Dip chicken in egg whites
coat in flour
deep fry in oil till cooked through

then melt 2 cups of butter, mix with 2 cups of Frank's Red Hot sauce. Dip wings or strips in this sauce!

That's it! No extra anything. I haven't tried it, but she has and she claims it comes out exactly like it.

Hope it helps =)
