The vibrant Thanon Sukhumvit Road, Bangkok's boulevard of dreams and plans, is the city's longest street. Stretching 490 km eastward into Cambodia, it ranks among the longest roads in the world. For most visitors, Sukhumvit Road primarily means the bustling section between Sois 4 and 33 – a veritable chaos of people, shops, woks, and nighttime activity. Travel writer John Borthwick offers a glimpse into this nighttime shopping and dining district in the heart of Bangkok.

The Sukhumvit Road sidewalk is a challenge: a chaotic jumble of stalls, utility boxes, construction sites, and food trucks. (A stroll here is more like an obstacle course than a walk—and that's precisely the appeal.) The street vendors, especially west of the Sukhumvit/Asok intersection, offer cheap clothing, pirated media, and all sorts of unnecessary but supposedly essential gadgets. Haggling is a pleasure here, but don't expect to get a better price.

A full-blown shopping experience on Sukhumvit Road is often a vertical one, spanning from mall to mall. Among the largest are the Emporium (Phrom Phong Skytrain station) and the gigantic Terminal 21 (Asok station). In addition, there are hundreds of independent shops and department stores like Robinsons. The malls are veritable complexes of franchises, offering brand-name goods of every kind—watches, cosmetics, shoes, fashion—from around the world. (Prices are fixed, so haggling isn't worth it.) The large, upscale EmQuartier mall (Phrom Phong) also houses restaurants, a cinema, and a high-end food court.

Avoid the traffic jams and take the BTS Skytrain directly. The Sukhumvit Line runs right along the middle of the road, bypassing the throngs of taxis, motorbikes, and tuk-tuks. The trains are clean and air-conditioned, though seat reservations are often required. A day pass costs 120 baht.

Taxis are readily available and inexpensive when absolutely necessary. However, make sure the meter is running. Tuk-tuks don't have meters and often try to charge tourists more than locals. Always agree on the price before getting in.

The area around the Nana (pronounced Naa-naa) metro station in Soi 11 comes alive at night, brimming with a party atmosphere. Besides bars and go-go clubs, Nana also offers numerous restaurants. There are also affordable tailors, though you should avoid the cheap "overnight" offers; a quality suit or dress requires at least two fittings and several days.

Perhaps it's because people don't get much sleep in Bangkok, but the city seems to be constantly eating. Sukhumvit offers one of the best culinary diversityes in the city, from five-star hotel restaurants to street stalls selling fried crickets and grasshoppers.

New to the scene is the Artbox Bangkok pop-up night market on Sukhumvit Road between Sois 8 and 10. The food trucks and stalls offer quick and delicious food (Mexican, Thai, burgers, etc.) as well as music and drinks. Ideal for families.

And don't be put off by the food courts in the large shopping malls – the quality is better than expected. At Terminal 21 (Asok Station), the food court on the fifth floor is among the best. Wherever you eat, be sure to try the classic Thai dessert Khao Niow Mamuang, mango and sticky rice.
