Kid Friendly restaurants in Northern MN/Heartland Trail area?

[vsoy]

My husband, my 18 month old son and I are planning to take a vacation in northern MN near Lake Itasca in mid-August. There are a few small towns nearby, Park Rapids, Nevis and Dorset. While Dorset is touted on a few sites as "restaurant capital of the world", we'll be missing the Taste of Dorset festival. The place we're staying at didn't seem too keen on Dorset, so I was wondering if there was anything chowish in that area of MN?

My son has milk, egg and nut allergies but he likes all sorts of foods. We'll be hitting the Carter's Red Wagon farmers' market for most of our home cooked meals. Any other suggestions for food shopping like supermarket, butcher shops? TIA for suggestions!
