They are very good with gluten free, have a specialized menu. Not so much for lactose intolerance. Server did not know if any of the dishes contained butter, and did not offer to go check with the chef. I ordered the flat iron steak, which came smothered in a spicy sauce. Had I known that, I would have asked for the sauce on the side. Was stuck with french fries as the only certain lactose free option. Would have preferred vegetables or roasted potatoes, but server did not know if eithe was prepared with butter. My husband ordered the hickory grilled sirloin, which turned out to be a very odd cut and not particularly tender. Server was very pleasant. As this was my third trip to Harper's and none of the times was there options for lactose free, I will not be back.
