Sukhumwit Road is one of the three longest roads in Thailand, leading right up to the Cambodian border in the East. But what concerns us here is the section from the inner city down to Sukhumwit 63 (Soi Ekkamai). The cream of this district lies around the entrances to the lanes (soi) off the road, where there are numerous fashionable residences, hotels, apartment buildings and guesthouses, and also a large number of really good restaurants. 

To the north of Sukhumwit Road is the extension of Phetburi Road, which is rather quiet in the daytime. After dark, however, the long street is brightened with colourful neon signs and enlivened by people going out to enjoy themselves in dozens of entertainment places scattered along the street.

There are both skytrain and subway stations as well. But while there are several skytrains stations along Sukhumwit Road, there is only one subway station at Asok (Sukhumwit 21) at which passengers can connect to the skytrain.
Royal City Avenue (RCA), a 2.5 km street between Rama IX Road and New Phetburi Road, is one of the leading entertainment hotspots of Bangkok. It has attracted teenagers and stylish people to seek amusement in numerous pubs, discos and restaurants here.
