I like eating at Sea Harvest. It's near the aquarium. It's relatively inexpensive, but the area around the aq is pretty pricey because of all the tourists around there.
There's also a liquor store near the aquarium (across the street from the Carl's Jr.) that has a deli in the back. The food is really inexpensive and quite good. The lady that runs the place is a hoot, too.
Avoid anything on Cannery Row. Expensive!
Avoid the margaritas in Pacific Grove... it's a dry city. Their margaritas are made with wine. It doesn't taste good. Trust me.
Don't forget to visit the fabulous cheese shop in Carmel.
