For Los Angeles, this is my one love 
SUI Croissants
For San Diego… I used to lived there after moving away from SF. Croissants at Izola is my ideal type (after testing everything we have in that lovely town). The key is they use my favorite pastry butter*
IZOLA

**Izola got a lot more famous these days and often sold out. Order online for pickup and enjoy the fresh baked one there with live music on the weekend. If you are looking for a dinner spot around, Callie restaurant is a block away with free parking and is my favorite spot in SD.
*Isigny Sainte-Mère butter - Beurre D’Isigny AOP: Our Pastrymaking Butters - Isigny Sainte-Mère
Beurre D’Isigny AOP is a butter pastry sheet made of unsalted cow’s milk in Isigny, France. It is made by churning some of Isigny’s best creams. These are creams which acquire all their flavor notes and organoleptic qualities during a vital stage in the production process: the traditional slow maturation period. The 1 kg butter sheet is especially adapted for pastry chefs who want to add a unique and exclusive touch to their croissants. It is just the right shape and ready to use. Its extreme malleability allows it to be rolled, folded, and turned for the perfect result. This product will help you obtain a croissant with a light and airy texture, as well as a subtle and inimitable scent and flavor of fresh butter. This smooth butter’s origin is protected by the AOC (Appellation d’Origine Controlee). One pastry sheet, 2.2 lb/1 kg.
