Flapjacks/thin pancakes on Westside?
Sorta like at OHOP in Redondo?
Kate Mantilini's in Beverly Hills and The Fountain Coffee shop inside the Pink Palace (aka "The Beverly Hills Hotel" on Sunset Blvd.) both come to mind. Not quite traditional west side, but if you can make it between 11 AM and 3 PM (or it might be 2 PM) and not on Sunday when they are closed, Musso and Frank's flannel cakes are thin and excellent...
