I went to the very first one and I have to say it was a blast. This is a monthly event that my friend hosts. It's pretty intense - you're surrounded by a whole bunch of other creative artists, drawing practically non stop. It has a pretty chill atmosphere and if you're interested to draw some costumed figures, this is the place to go!
Here's a link to some of the sketches I did that night: http://nocturnalconcept.blogspot.com/2009/03/metemorphica-workshop.html
And for more info, here's their blogspot that has a whole bunch of pictures from previous events and other people's drawings: http://busstopgallery.blogspot.com/
