We have tried a few and here are my thoughts so far ...
El Sol De Mexico: Good food, clean, nice family running it, we'll go back
Nacho Mamas: food was pasable, place was very dirty, won't go back
Chevy's: Standard Chevy's, good food, cleaner than some, nice atmosphere
Pacific Breeze: (Thai) Very good food and service
Teriyaki and Bento place in King City - decent fast food.
I won't comment on the chains much, but we have eaten at McCormick and Schmicks and it was great, CA Pizza Kitchen (love the chicken waldorf salad sooo much), PF Chang's is always good anywhere, there's a great little noodle place in Bridgeport Village that is tasty, and the Arbys on Pacific Hwy is very clean and pleasant for a quick sandwich.
