I need to order several sheet cakes for a party. I was thinking about going with the Mayfair Market. Can anyone offer any other suggestions? I know also about Costco, but I would like one with real lemon curd filling (not the icky yellow gel filling). They don't need to be decorated, just plain vanilla buttercream. I haven't decided how much I'm willing to spend, so price is open. I would prefer not to travel all over LA, so downtown and west preferred.
