Mumbai?s bus service, run by the Bombay Electric Supply and Transport Company (BEST) is one of the best in the world. The BEST network is exhaustive and links virtually every point in the city to any other. (Booklets on the various routes are available at many book stores and railway stations). The buses, especially the stately double-deckers look like slightly run-down cousins of London?s original omnibus, but they are cheap and safe. Avoid the office rush hours (9 am to 11 am and 5pm to 7 pm) if you can, unless you?re something of a sumo wrestler. Incidentally, outside office hours, the top of a double-decker provides an intimate view of the metropolis and is a great way to explore the city.
