Red Robin claims to make gourmet burgers and a couple of them are alright. They even have one with a fried egg in it. I think they are OK but I know several people that love them.
Fuddruckers was the best one in Orem, until it closed about 1.5 years ago. :-(
Red Robin in Provo is the best in the area I've had since then; sadly it's not at all close to where I live.
