HONK PLEASE !!!
One of he local custom in New Delhi (probably entire India) is to keep honking while driving, just keep hitting the car honk endlessly. This is not a joke, almost all the big trucks on the street or highway have a big HONK PLEASE written at the back for other drivers to see and read, so that they can honk and honk, amazing local custom.
The Indian version of the "tuk tuk"
One of the more popular, economical and pleasingly Indian ways of getting around in Delhi (and other major cities for that matter) is by motorized three-wheel rickshaws, which the locals refer to as auto-rickshaws. In most larger Indian cities, these little rickshaws swarm like mosquitos in and around the busiest streets and traffic jams you can imagine. In what seem to be a somewhat successful effort to reduce air pollution, most of the auto-rickshaws run on compressed natural gas instead of gasoline. You'll notice a little sign on each of them that says "CNG" for compressed natural gas.
If comfort and luxury are your bag, you'd best pass on the auto-rickshaws. They're coverd, so you'll be protected from rain and direct sun. But, they are not sealed to external temperature, noise and clamor. In all honesty, I can't imagine how these auto-rickshaws are safe or fit for more than four passengers, in addition to the driver. At that, four is a tight fit. THAT being said, I have literally seen rickshaws carrying no fewer than 15 Indians crammed tightly into them through the Delhi traffic. Considering that they have very small engines, let's just say that it's a stuggle for a fully loaded auto-rickshaw to get up a hill.
In another tip, I advised that you never buy the "my meter is broken" line from a cab driver. It's a different story with auto-rickshaw drivers. Truthfully, most of them ARE broken.... sometimes broken deliberately by the drivers. You are going to have to negotiate your price, and I suggest that you get things perfectly clear. It might not be a bad idea to write down where you want to go on a notepad and then ask the driver to write the price onto the pad. If you're obviously not a local, you will be quoted a much higher rate for transport, so you can barter a bit. But as for "much higher", it's relative... by western standards, even the exorbant price the rickshaw driver may quote you will seem quite reasonable.
Generally, short trips will be about 30 or 40 Rs. For a trip across town, maybe you're talking 100 Rs, which is a hair over US$2. So, you won't go broke riding in auto-rickshaws. Just get the price settled before embarking on your journey.
Humayun’s Tomb is a superb example of early Mughal architecture. Actually you can find 2 main tombs here. The first one is the octagonal tomb of Isa Khan, the second and biggest one is Humayun’s Tomb, which was built by his senior wife.
The gardens around it make it a very peaceful place in hectic Delhi.
Jami Masjid (I)
Jami Masjid is the largest mosque in India situated right in the middle of the Islamic community in New Delhi, which comprised a significant proportion of the population. Naturally, it is better to avoid visiting the mosque during prayer times unless you want to share your space with 25,000 other people. Enterance is open only from the south and north gate except on friday and Muslim festivals when the larger eastern gateway is also opened to the public.
Presidential House (Rashtrapati Bhavan)
Rashtrapati Bhavan is located at the far western end of Rajpath and is the official residence of the President of India. Built on a very large scale - 600 meters long and 180 meters wide - it was the former residence of the Viceroy of India during the British Raj. Lord Irwin was the first occupant of this building. It was designed by Sir Edwin Lutyens and built on Raisina hill, which he saw as an Indian Acropolis with the Viceroy's house as the Pantheon. Bigger than any palace of Indian princes and one of the biggest palaces of the world, it has a large court to its front and a Mughal style garden at its back. Built in a neo-classical style, it has 340 large rooms, 37 salons, 74 lobbies and loggias, 18 staircases and 37 fountains. The iron gates, (which is as far as you can go), are copied from a pair that Lutyens saw in Chiswick, England.
