Vintage Bike Night at Bauhaus tonight? The museum your friend speaks of is the Mill City Museum. Built into the shell of the old Washburn A Mill. That's right by the Guthrie Theatre and the Stone Arch Bridge, all of which I recommend. Great way to spend a couple of hours. The first floor of the museum is free and open to the public. The Guthrie has a walkout balcony with great views of downtown and the river. If you want to see how Minneapolis got started, this is the place. There are lots of good restaurants right by Target Field. Smack Shack, Parlour, Red Cow, Red Rabbit, 112 Eatery, etc. I'd recommend downloading Yelp or Tripadvisor on your phone and searching for things that are near you. The Twin Cities has a fantastic food scene with a fantastic restaurant in almost any genre. Butcher and the Boar's Beer Garden will give you a free pint with a Twins ticket, and has a fantastic burger. Unfortunately, there are not many motorcycle, railroad, or aviation themed things to do close by that I've found so far. Hope this helps!
