Lambretta, if your boss is looking for good, high end places, I'd suggest Spago (Beverly Hills), Josie (Santa Monica) and A O C (West Hollywood). As for Thai, I think the best Thai in Thai Town is found at a very simple, BYOB place called Ruen Pair (for example, you can get fried morning glories there) on Hollywood Blvd. For a more upscale atmosphere, and alcohol, another choice would be Jitlada on Sunset.
