Atmospheres. Depends on what kind of environment you would like to experience. Downtown more businessmen, west Hollywood, hip and trendy and Beverly Hills - well the home of the rich and shameless. Once you pick an area, happy to offer restaurant suggestions

...the beach to downtown and from LAX to the Valley.  Plenty of restaurants to choose from and easy access for the guys.

Culver City
West Hollywood
Mid-Wilshire

And in the valley:
Sherman Oaks
Studio City
North Hollywood

Parking sucks in Beverly Hills.

Parking and traffic are horrible

my favorite incall spot is west la.  convenient to 405 & the west side (i'm in the valley, so it's an easy drive).  plenty of great hotels.

hope to see you then!
