The Happy Gnome looks like it has potential.
Happy Gnome is good. Try working your way up to NE Minneapolis. Dangerous Man, Indeed, 612 Brew, Bauhaus, Sociable Ciderworks, and a new one I haven't been to Able Seedhouse. That's 7 breweries within about 5 miles. Then go get a 2lb gyros from Holy Land Deli on Central.
Want food? Go to Matt's which isn't overly far from the Convention Center, or even The Nook. Both are known for their Juicy Lucy burgers. Obama ate at Matt's. Both dive bars. Stub and Herbs on the U of M campus has a pretty good tap list and also good burgers. If you want some awesome/authentic Korean food, there is a place next door called the Korea Cafe.
Not overly far from the convention center is Hell's Kitchen. Awesome breakfast place as well as a good happy hour menu. I have a feeling Key's Cafe will also be a popular breakfast destination. Minneapolis is really a foodie town, lots of places. Butcher & The Boar (also awesome beers), Bachelor Farmer, Haute Dish. I'm pretty damn excited as you can tell and happy to share any knowledge.
