Sampeng Lane (also known as Soi Wanit), running parallel south of Yaowarat Road, and the narrow lanes directly off it, are a riot of colour and noise. Here you'll find garments, textiles, stationery, second-hand parts and equipment, electric goods, kitchen utensils, computer parts, antiques and even car parts, musical instruments or ancient Chinese medicine.
Merchandise is generally very cheap and, often, sold wholesale. Sampeng Lane was previously infamous for the gang fighting and high numbers of murders that took place here. Nowadays, it's a very busy and predominately pedestrian street, with the main danger being the odd motorbike that tries to get past. The street is a hive of constant commercial activity, all day long.

The Thieves Market, or 'Nakhon Kasem', is slightly north of the western end of Sampeng Lane. Though legitimate today, it was so named because this was where stolen goods inevitably turned up. It's now a good area for buying Thai or Chinese antiques. Following the river heading north, Chinatown gives way to the wafting aromas of curries and the exotic spices of Pahurat.
A small but significant Indian community is located around the famous Pahurat Textile Market on the edge of Chinatown. Wholesale silk, cotton and all kinds of fabrics are traded with tough bargaining skills. Its also a good place to head for if you're desperate for some authentic Indian food. The markets are generally open throughout the day until around 18:00.
