I don't know why so many people are anti chain restaurants. Maybe it's because I grew up in the 'burbs eating at them but I have no issues with them like some people do.
Macaroni Grill is good. I love the "create your own pasta dish" concept.
Claim Jumper. Huge menu, huge portions.
Bobs Big Boy. It's a classic! Especially the one in Toluca Lake (near Burbank).
High end, Mortons and Ruths Chris are great!
