Mugsy's has pretty good food. On different occasions, I've had BBQ chicken, ribs, and pulled pork sandwich, and they were all very good and filling. I know people that swear by their wings, but I've never had them myself.
Lots of televisions to catch multiple games on, although some of the seating is in awkward places to get good viewing angles. Keep that in mind if you're going there to watch a certain game.
It can seem a bit cramped when it's busy, but when it's a little less full it's got a nice atmosphere.
