Ok, Proud Bird is basically a week-day place & TelevisionTdTina did a good job of getting us out.
On the weekends - which is when most LA FTers get together - it's Manhattan Beach area etc (which is either convenient or mutually inconvenient for all).
There are obviously other things to do (Freddies Friday for example), but basically if you're serious about people getting together, check the Community calendar & just pick a weekend & post that THAT is the time to get together.
You also need to determine if you're going to make it a dinner only in which case you'll get locals, or if you're going to build it up into a 'do', in which case more happens/etc.
Cheers.
