I'm meeting up with some five girlfriends on Friday for happy hour. My cousin is in town and I want to go somewhere lively and fun - so she gets a taste of LA. Most of the happy hours we know of end on the early side and we are all coming from work. Any suggestions for places in and around Beverly Hills/West Hollywood area (nothing east of The Grove/Larchmont though)? We've been to Cha Cha Chas a few times now and are looking for some other ideas. Late happy hours are great too.
