The Event Center is moving (and changing names to Games Center) about a block away. I think Google maps is totally wacked for mapping addresses on that street, but look at HOM Furniture 2480 Cleveland Ave Roseville, MN 55113, just to the east of that is a CARQUEST. Just to the east of that is the new Games Center. The Radisson is the closest hotel to stay in (and probably the best as well).
The street view data is old (it's under construction):
The Games Center will have a full real menu, but I'm sure you will want some variety. A few blocks away is a large mall (Rosedale) with a few good food options. It's not a terribly far walk, but it can be cold in November (it all depends, who knows). You should be able to catch a ride over to alternative restaurant options with other gamers.
