Buffalo flavor is available in three levels of spiciness: mild, medium, and burnin' hot (personally I would have named my hottest flavor "ragin' inferno" or "novacane substitute" but that's just me). I chose to go with "medium." Buffalo sauce (and wings), by the way, is named after their city of origin: Buffalo, NY, and is basically cayenne pepper hot sauce and butter or margarine.
Also they didn't offer us any Ranch sauce! How can I eat Buffalo Wings with no Ranch sauce?! Celery and carrots sticks would be nice as well.
