I tried to send feedback directly to Red Robin, however their web-page doesn't accept feedback. Bottom line, there was a hair in my burger. I try to be rational and understand that these things happen. But this was a gross one. I was eating with others and didn't want to gross them out, so I tried to pull the hair out without issue, however it was very long, dark, and stuck throughout my sandwich. It was in the cheese, which had since dried up making it immobile, and I had to remove all the condiments to get to the full length. At that point I was beyond grossed out and threw away my order. I spent $26 on lunch for myself and a co-worker and didn't get to eat it.
