For hassle-free travel within Delhi
Word to the wise: Except at railway stations, you can't hail a cab easily in Delhi. Look out for official taxi stands in neighbourhoods - ask for the meter or negotiate the fare before departing.
If you can't quite face the city's auto-rickshaws, taxis are still an affordable transport option. You can hire a radio taxi cab via a reputable firm like Mega Cabs or Meru Cabs, both of whom also offer online booking.
If time is short, hire a chauffeured car for added convenience - most companies offer 4hr half-day or 8hr full-day services. It is relatively cheap and makes getting around the city a thousand times easier - you can go where you like, when you like, and avoid the inevitable haggling that accompanies hailing a rickshaw every time you need one.
