As others have mentioned, Napa Rose is fantastic. Most of the times when we do go, we sit in the lounge area and order 1 or 2 of the mushroom soups and perhaps 1 or 2 other apetizers (and share it all). It's quite relaxing, and imo one of the best restaurants in orange county.
PCH grill at the Paradise Pier hotel is pretty consistent. 10-15 years ago, they had these awesome wasabi mashed potatoes. They've changed the menu since then, but I've never had a bad meal there, either.
Blue Bayou is always fun, although it's annoying how they've increased their prices over the years!
I also love the apple pie caramel apples (and the churros always taste better at the parks)!
