Patpong 

After recently cleaning up its act, Patpong's become one of the 'must' night shopping destinations for avid shoppers. The place is always busy and chaotic with all the commotion from the GO-GO bars nearby and lots of foreign tourists. This market in Bangkok's notorious nightlife district is often the first and easiest stop for many tourists just arriving to Bangkok, whilst lodging at one of several mid-to-upper-end hotels in Silom. Be warned though, the quality and prices of most items sold are about as real and trustworthy as the girls shaking their wares in go-go bars flanking the area. Both market and go-go bars seem to complement each other well, but remember not to be fooled by first impressions, and to bargain hard.

How to get there: Coming from BTS Siam station, depart at Sala Daeng station and exit down one of the right-hand stairs. Follow the increasing trail of vendors along the sidewalk, and after five minutes, you'll know you're there.
Items at market: Cheap 'brand-name' items, CD's, souvenirs, T-shirts, etc

Open: 18:00 - around 01:00 (every day)

Suan Lum Night Bazaar
A mixture of poshly dressed, fresh-from-the-office Thai's and expats along with fisherman pant-clad tourists, Suan Lum could best be described as the VIP outdoor market of Bangkok (where you're always welcome, of course). Covered walkways with centrally-located snack bars provide perhaps the most luxurious (outdoor) market shopping experience in the city. Several bars along with Thai, Italian, German, and even Mexican restaurants are conveniently within the market area, close enough to analyze the crowd while enjoying a drink, yet away from the market's hustle-and-bustle. In the same area, dinner shows featuring classical Thai puppetry can be enjoyed at the famous Joe Louis Puppet Theatre.

On the other side of the market's curious Khmer-looking temple walkway, lies a large outdoor beer garden, food court, and concert venue all rolled into one. Here one can indulge in an assortment of inernational and Thai beers and foods, with international fare either Japanese (yakitori and Asahi) or German (sausage, Paulaner, etc). Beer and food are accompanied by live Thai cover bands performing the latest local and international hits on stage. Also, don't forget to check out the Big Wheel, 'La Roue de Paris' while you're there! And, after a few drinks with friends, head out to one of Silom's many nightclubs.

How to get there: Take the MRT subway to Lumpini station; the market is near Lumpini Park, a short walk from the station.

Items at market: Creative gifts, trendy home items, clothing/jewellery boutique shops by local designers, packaged dried fruits, a few stalls selling the usual market CD's/clothing.   Open: 18:00 - 00:00 (every day)
