Bangkok the capital of Thailand population is 11 Million. This is a very cosmopolitan type of city with people from all over the world. Most Asian stock markets are reported from Bangkok. It is an International destination hub for all international flights. The country is ruled by it's king and queen, but does have a standard form of government. The official currency is called the baht and the US dollar conversion rate is 30 to 1. 30 baht to a dollar. So roughly 100 baht is $3, 1000 baht is $30. There are two major tourist areas of interest to US citizens, one being Sukhumvit Road Between Soi 6 and Soi 21 (the middle of the two most popular Red Light districts, Nana Plaza and Soi Cowboy) the other being the Silom area where the State Tower, Peninsula Hotel, Mandarin Oriental, Shangri-La are all located by the Chao Phraya River. The 3 level Restaurant and bars, called Lebua, on top of the State Tower is where the Hangover 2 was filmed. It's a popular tourist destination with spectacular views of all of Bangkok. The top restaurant is named Mezzaluna. A true five star restaurant which only serves tasting menus. Cost is around $250-$400 per person. The open air restaurant Sirocco is where the Hangover 2 was filmed for the big final helicopter scene. Cost of dinner is $100-$250 a person however you don't have to eat you can simply go to the outdoor bar, order drinks, and ogle at the magnificent views.
The Sukhumvit area, around Soi 10, has some of the newest and most fashionable shopping malls and parks that you can imagine. Additionally there is a raised Tram system call BTS which connects the two areas together very quickly and inexpensively. As you can imagine traffic in a major city is overwhelming. Sukhumvit is a divided into 2 one way streets going in opposite directions. And turnarounds do not exist on every corner so if you're going in the wrong direction you may have to go 10 blocks out of your way just to get to the other side. You may find that the fastest way to travel is by foot if it's only a few blocks. And remember, as in England, Thailand streets are opposite from the US. Do not be foolish and rent a car. It is cheaper to rent a taxi and there's no place to park. Of course if you want to have a little fun you can simply jump in a Tuk-Tuk and just ride around. Taxis in Bangkok are metered but at night they turn off the meters in order to earn more money so before you get in any vehicle always ask the driver how much for the ride. That goes especially for the Tuk-Tuk. If the taxi is metered you won't have any problems. The cost to hire a taxi is incredibly inexpensive so even if you got ripped off it would be for dollars not hundreds of dollars. Additionally there are private drivers you can hire for the day at a very minimal cost. The cost of a taxi from Bangkok Airport to any hotel around Sukumvit Soi 10 (25 minute ride) area is less than $20.
