There is a Kwik trip just up the hill on I90 in Minnisota, Exit 266 on the south side. Has a cafe with decent grub and showers. @ 12-15 mi back down to LaCrosse.
Stayed at the Centex at exit 12(north side) nice people but it's a bit spartan.
Don't park facing the fuel isle at night, those lights are brighter than anything else for 20 miles.
Probably should have parked in town though, it seemed like a nice place and there were plenty of spots to put a rig.
