Thanks to Nancy for emailing this recommendation:
Bob Evans in Lexington KY was absolutely wonderful. Attributes included: the server knew what to suggest, the server checked it out with the chef, the chef cleaned the grill before cooking (I had salmon & broccoli).
The Bob Evans restaurant chain was born out of the Bob Evans Farm in southeastern Ohio, and the restaurants are still serving a full farm-style menu today. They offer detailed allergen information on the Bob Evans website for the top allergens, gluten, sulfites, and MSG – so it appears that all locations do their best to be allergy-friendly. Though Bob Evans has many dairy items, they do offer several selections on their dinner, lunch and breakfast menus (according to their website) that do not contain milk of any kind.
Bob Evans restaurants are located primarily in the East North Central, mid-Atlantic and Southern United States. See their website for locations, phone numbers, hours, and full menus.
