My wife and I booked a Friday night tour (8/5), and we both agreed by the night's end that this was an absolute highlight of our trip to Minneapolis. Our driver Eric knew his stuff, was easy and fun to talk to, and kept the beers flowing for us.
We stopped at 3 places (Harriet Brewing, Fair State Brewing Cooperative, and Sociable Ciderwerks). All 3 were quite different and quite enjoyable, and there are food trucks outside to provide some eats. Eric's beer recommendations never failed. The group we were with was fun and easy to talk to.
Overall, I highly recommend and would do it again if we're in the area in the future.
