A cab pretty much anywhere around town won't cost you more than 21 yuan ($3). The cabbies generally don't speak English. Attached is a checklist, which was handy, which was made available from the conceirge, but may not be available at every hotel. I would just point to the taxi cab driver.
The only one that I had a problem with was the Fabric Market. Cab drivers may not know where this is, as it moved within the past two years. Many books (including my Lonely Planet) can become quickly out of date.
It's rather easy to find one of the city's 45,000 taxicabs (except when it's raining), but they drive a bit crazy (but not as crazy as Egypt). I'm surprised there weren't more accidents. We constantly had near misses.
Different cab companies had different colors. Some are good and some are bad. The good ones were teal, dark blue, and yellow.
