Are you looking for something right downtown near the target center or are you going to be partially mobile?
There is a champps downtown which is a decent place to watch a game (advantage their food is crazy good, try the club sandwich)... don't really remember where but its within a few blocks of the target center on 1st ave. There is a place called Macks or something like that NE minneapolis as well that is good. Big10 bar has two locations, one downtown off washington ave and one on the Uminn campus (forget where), both of which are ok choices.
Outside downtown, Joe Sencers is good for a game, but its all the way to 494... north of the cities there are a couple of buffalo wild wings, which I have a weakness for.
Be aware that all of these places will probably show the game, if it is on at the same time as Minny is playing you will probably not be the showcase game on.
