The Thai restaurant (Siam) in Westchester that lisamcgu mentions is a good location, good food (and a LOT of it), good prices & is an FT hang-out when folk have flights departing in the evening (5 minute drive from LAX), so I'd say dinner there would be a good choice for everyone. They have a hot sake machine which lisa loves.
For those who want to do lunch in MB & not spend too many $$, there's lots of options. If you want the direct view of the ocean, then Beaches overlooks the pier. Also on Manhattan Beach Blvd is a pizza place (just up from Beaches), The Kettle, Hennessy's, Shark's Cove (where we were in June), Rockfish Tavern, Manhattan Brewing Co, and something else I'm forgetting. On Manhattan Ave there's also an Italian Place (follow the garlic smell! think it's called Mama D's), a fish taco place, a Italian/Greek place, mexican place (sorry, can't remember their names).
Have fun all - see you next time DEK. Cheers.
