Review of Iowa Chop House

I was so disappointed with this restaurant. I ordered the chicken on a gluten free bun. When they placed it on our table it smelled and looked good. Then we noticed they had put breaded onion rings on it. We complained to the staff and the manager was going to come talk to us. She/he never did and had the waitress come to our table. I obviously couldn't eat it. They didn't charge my husband for his meal and I had to find something else to eat since I didn't trust them after that! Just because a restaurant has a GF menu doesn't mean the cooks understand what that means.
