For the newbies - the weekend market at Chatuchak is really, really good people-watching territory. Your Thai acquaintances may refer to it as "JJ", and an alternate alliterated spelling is Jatujak.
It's an easy and enjoyable morning out alone if you aren't with someone, too. Take the BTS to the Mo Chit end of the line station and just follow the crowd. I've read estimates that it's around 25 acres, between 10-15,000 stalls and gets between 200 to 300,000 shoppers every weekend.
You're quite liable to see most everything you can imagine (and some you probably shouldn't) for sale there. There are ATMs available, but I've often been cautioned by my Thai friends to keep a close eye on my wallet and valuables - so let the shopper beware.
I get there by 8:30 at the latest and get the hell out of there by noon. It's unpleasantly hot for me by 11:30, usually. I highly recommend staying hydrated while there, as is wise most any time you're out in the sun/heat in Thailand.
There are a number of photos from the market in my photo album here, back in the earlier pages.
