Make sure to hit The Electric Fetus in Mpls and Into The Void in St Paul for awesome local record shops. For food, I would definitely hit all three of these places for the best iconic Mpls meals: Micky's Diner (St Paul, very very near the Excel Center) and Matt's and Anchor Fish and Chips in Minneapolis. All cheap, all incredible, and all very much Minneapolis. While you're at Anchor be sure to head across the street to Dangerous Man Brewing for some super delicious, super fresh and very cheap local beer.
As far as clubs, try the Triple Rock, The Hexagon, or the CC Club, and as always, First Ave is king.

My band Fallen Empire was trying to book a show for the 27th, but to no avail. We're looking at getting some EITS folk and local friends to your studio instead. PM me if interested.
