The Green Mill - DS (PA) has done okay there in the twin cities but has only been once or twice. I had a reaction there (shrimp). It's not hard to have shrimp cross contact reactions in restaurants, though.
BWW - DS does fine there but he is a vegetarian and only eats vegetarian food there.
Perkins - DS has done fine there and goes with friends after 9:00. He gets hit and miss savviness at the Twin Cities one he goes to.
Qdoba, Jimmy John's, Wendy's - yes and very good with FAs.
If you go through the Twin Cities, Davanni's is amazing. The Minnesota FA group has several evenings at Davanni's each year.
We love Hello Pizza in Edina.
