I got invited to one. A room full of strangers, two close friends, and -from what I gather- lots of packaged processed food. I've been to candle parties and "adult toy" parties, but never one of these with the foodstuffs. I'm feeling all xenophobic about a group of people that gather in a home to buy drink mixes, and dip. I have to go, one of my closest friends is hosting. I'll eat anything, though. I ain't too proud for convenience food.

Is it any good? Tell me about your experiences at these things, and what to expect, please? What to look for? What to avoid?
