The Red Robin is close to my office so I go there several times a month. They have the best burgers I have ever eaten.
Sometimes it takes a while to get waited on. But the wait is worth it.
I have noticed one thing that seems to occur on a regular basis. The bartenders make a lot of noise when they drop the plates in the container for the kitchen help to pick up. I usually sit at the bar so I can watch the TV and it is very noisy.
