There are three kinds of taxis -- general taxis, deluxe taxis, and call taxis. The last two types of taxis offer a high standard of service compared to the first, but are more expensive than the first. You cannot always expect that a taxi driver is fluent in English, so it is advisable to tell the landmarks (many major hotels and attracts) near the destination. Vacant taxis have indicator lamps on, in front of assistant driver seat and on the roof.
