Oh, I thought it was a joke about the buffalo circle thing.
Are they worth free though?
Sure. Especially (or only) the boneless wings. BW's boneless/ chicken chunks are still some of the better chicken chunks among all the competing sports bars and wing joints.
They have good sauces, but their regular wings really aren't all that awesome in terms of size. I'm not a major wing fan anyway, well, actually, I can't stand drummies, and usually ask for "all wings" if possible whenever ordering wings. I can't stand dealing with bones and tough connective tissue, and drummies have a terrible amount of connective tissue for my tastes. :\ I'm not a big bone-in chicken fan though,.
The snack size is puny for my metabolism. It's 5 wings, or 7 boneless. Nice free add-on for another meal though, or as a post-dinner meal out getting some drinks watching the game.
