Seeking information about restaurant my great-grandmother owned

I would start by looking for her in city directories for St. Paul MN for the time period she may have owned the restaurant.  If there are two addresses for her, one would be her home and one her place of business, although often people lived at the same location as their business.  Then try to match the address(es) with those of restaurants in the city.

Dear Ms. Bonk,

Thank you for posting your request on History Hub!

To further the information from the previous poster, we suggest that you search for the St. Paul city directories online at Ancestry or Fold3.  There may be a fee for these services. Instead, please check for access at your local library as many library systems subscribe to these sites, making them free for their patrons.

We hope this is helpful. Best of luck with your family research!
