I just went to Red Robin a few months ago. When I walked in I realized WHY I had never been there. It's a family friendly joint - so you never know when little junior will start screaming or running through the aisles. Thankfully, that only happens about 20% of the time I'm there, probably because I'm there on weekdays for lunch.
I have to admit though, they have consistently good food. Not creative, just basic stuff, but tasty. The salads in particular are really great (and I'm picky about lettuce and salad dressings). Plus they'll bring you fries for free - all ya have to do is ask :-)
My co-workers won't let me stop going, but then again I don't fight them too hard.
