for what its worth...i've been to a few. there is one this thursday night. they are usually at the Peugeot lounge in Pal hollywood. usually gets packed (150-200) and is fun for the most part. can be a bit cheesy and definitely dominated by americans late 20's.
even with that many people who don know its each other, its still very cliquey...
they are publicized on FB, if you "like" their page, they will invite you. u need to rsvp to be on the list.
this is a means of income for the bubble, as they do very little advertising. they use the 100pesos entrance fee towards paying their writers.
