Went there last night to celebrate my son's track meet. Got there about 9 pm so after the dinner rush. We were seated right away... at the absolute filthiest table I have ever sat at. The entire floor in that section of the restaurant was covered in garbage. There were 4 tables that sat with dirty dishes for at least 30 minutes.
Our waitress that we started with told us that she was being sent home. But she stayed and served the table next to us for the remainder of the night. Our waitress was good, and the food was good, which is the only reason they got 2 stars. The bathrooms were also filthy and the trash probably had not been emptied in hours.
The guy I saw bussing tables did half a table and then left to do God knows what. My husband (who loves Red Robin food as much as I do) said we likely won't be going back. This place belongs in the worst part of the East side.
