Wings and Beer for Patriots vs Cowboys
Want to find a fun/cool place to watch the Big Game. Good food is a plus. Sports bars can be very chain-y but would like some festive atmosphere.

Bad news - It defintely looks like a chain restaurant with poor food quality to match; although, to be fair, I've never tried it and most likely never will voluntarily (unless I was a die-hard Cowboy fan).
