What was the grand opening date of the Joe's Crab Shack in Roseville MN where the black lynching photo was discovered embedded in the tabletop?

I searched for quite a while looking for when the Joe’s opened in Roseville, and I can’t find a year, much less a date.

I’m curious how many people were exposed to the photo before it was reported and became an issue.
