Ploenchit and Chidlom are the upscale districts of downtown Bangkok, where you can find rows of high-rise offices, upscale apartments, embassies, expensive shopping malls, and 5-star hotels. The area is low on traditional tourist attractions (other than several popular shrines), but high on chic and prestige.
During the day, it's mostly about shopping for the designer, status-symbol variety but there’s always a casual wine bar or down-to-earth cafe to rest your feet. The areas are connected to the rest of the city via the Phloen Chit and Chit Lom BTS Skytrain Stations, both of which have covered walkways to famous Bangkok shopping malls.
