I'm not from grand rapids, but the last time i was there mulligans seemed like a pretty sweet wings bar. awesome drink specials (pitcher of PBR for $4 all day every day) and tons of wings stuff on the walls.
mulligans is cheap (and smelly sometimes) but it is fun. However on a friday night, it is much more likely that they will have a live band rather than the sound of the game on. Any sports bar should be playing a wings playoff game i would hope.
