I was thinking about this very topic ever since yinzer claimed there were no good wings in DC.
I love the wings at Austin Grill, but they are definitely not Buffalo wings.
For Buffalo wings, Ruby Tuesday's does alright if you can put aside the aversion to national chains.
The best wings evah were at Chuck's Spring Street Cafe in Princeton, NJ. Granted, it's been 15+ years since I was last there.
