Perhaps the easiest and most comfortable way to get around, if not always the quickest, is by the aircon taxi. These come in quite a few different colours though the green-yellow and red-blue ones are the most common. Bangkok has thousands of taxis, and finding one at any time is never a problem. The occasional exception to this is during a monsoon season downpour. By international standards they're very cheap too, the flagfall rate is 35B (0.85 US$ approx) including the first 2km and it's 5B/ km after that. This means that even relatively long journeys, such as from Sukhumvit to the Grand Palace often aren't above 100B (2.5 US$). A surcharge is applied in traffic jams (1.25B/m when moving under 6km/h), meaning at night when there's not much traffic they're definitely the best way of getting around.
