I am a fan of this place, definitely. The only thing is that the last time I went, the service was bad. My waitress forgot about little things I asked for, which I think she realized after a while. Then she apologized, after a different waitress took care of my requests.
The menu has lots of different options. Lots of burgers, sandwiches, and drinks. The burger buns can be substituted with a soy bun also.
It is often crowded, but the place is kept clean. I like Red Robin.
