IMO, all the chain steakhouses are overrated - Mortons, Ruths Chris, etc.
Not all of these are fancy sit-down places, but as far as the food itself goes, all are highly recommended.
Anaheim White House, Orange Hill Restaurant (technically not Anaheim, but very close), The Ranch, Roys, Okayama…
+1 on Ma's. Definitely not fast food Chinese like the other spots noted here. A little on the pricey side, but big on flavor and they have some unique northern Chinese dishes.
