If there is a person you are going to see in Grand Forks, I'd ask them first (whether it be a client, vendor, family member, doorman, front desk, cabbie, etc etc)
Seeing as Grand Forks is 'out of the way' a bit, my guess is it isn't covered on most food blogs.
So if asking doesn't get you anywhere, I punt:
