Culver's has been a good experience when I have gone. They keep the gluten free bun separate in the package, so you know it hasn't been contaminated. Never had an issue with ordering a burger and plain custard here. Fries use same fryer, so avoid, staff has been knowledgeable about this whenever I come. Got the mashed potatoes once without gravy and did not have a issue.
