I agree mostly with ericQJames in that I would not stay at the Four Seasons. It is nice, but it is just a city four seasons when it comes down to it. The Pen is very nice and has a great rooftop, but is relatively new, and as noted, does not have a connection with the city (although when CAA was located next door, the bar after work was about LA as it got). Between the BH and Bel-Air hotels, I would say it depends on what you are looking for. The Bel-Air hotel is known for being very secluded and quiet. The BH hotel is larger, and has more of a bar scene.
