Anyplace we ate in the Gaslamp District was very good, and reasonable I thought. There was a Mexican place on a corner there that had great ceviche, as did the Tin Fish across from the convention center. The Strip Joint (steak) looked good, but we didn't have time to get there on this trip. Another place I intend to try when we're back is the Stone Brewery restaurant.
Cass St is still a great place and one of my favorites. If you like Cajun food try Chateau Orleans. It's in north PB. They normally have a 2for1 coupon on the Reader that comes out every Thursday and can be picked up at most grocery stores.
Hodads rocks! As far as I'm concerned, it's the best burger I've ever eaten. Get there right at 11am for lunch and the line won't have formed yet. After lunch, head to the right out the door and stop at the first door you come to after the parking lot. Fantastic chocolate goodies!
