Delhi (also known as the National Capital Territory of India) is a metropolitan region in India that includes the national capital city, New Delhi. Delhi is a city that bridges two different worlds. Old Delhi, once the capital of Islamic India, is a labyrinth of narrow lanes lined with crumbling havelis and formidable mosques. In contrast, the imperial city of New Delhi created by the British Raj is composed of spacious, tree-lined avenues and imposing government buildings. Delhi has been the seat of power for several rulers and many empires for about a millennium. Many a times the city was built, destroyed and then rebuilt here.

Shopping in Delhi -
From medieval period, Delhi has always been the most important trading center in Northern India. Many of its localities, like Sheikh Sarai and Yusuf Sarai, derive their names from the ancient trading towns of Delhi. Today, instead of market towns, there are number of shopping complexes, hubs, wholesale markets scattered all over the Delhi city.
There are whole shebang of items of tourist choice, such as jewelry, carpets, handicrafts, precious stones, silks and silver ware - all synonymous with India. Connaught Place, Karol Bagh, Sarojini Market and Chandni Chowk are the principle shopping areas. Baba Kharak Singh Marg, near Parliament Street is dotted with multiple emporiums, offering the famous handicraft artifacts of different states of India under one roof at government-controlled prices.
To know the real culture and traditions of city, the best way is to stroll or wander around through its market places, for it is here that contemporary culture is most visible to the visitors.
HOW TO REACH HERE
Indira Gandhi International Airport, (IGI, IATA: DEL) , located in the west of the city, is the arrival point for many visitors into Delhi. Once notoriously bad, since privatization the airport has been extensively revamped and, with the opening of Terminal 3 in 2010, has been transformed into a thoroughly modern facility equivalent to the best airports in the world.
Buses arrive from Kathmandu and Chitwan in Nepal (36 hr+) and virtually every city in India. Although not as comfortable as the trains, buses are the only choice for some destinations, mainly those in the mountains. Delhi has a confusing slew of inter-state bus termini (ISBT), which all have two names. The Delhi Transport Corporation  is the major operator, but every state also runs its own buses and there are some private operators too.
Trains arrive at one of four main stations: Delhi Junction, also called Old Delhi or Purani Dilli; the second at New Delhi which lies in Central Delhi; Hazrat Nizamuddin a few kilometers to the south; and the upcoming Anand Vihar station to the east (very few trains use Delhi Sarai Rohilla or Delhi Cantt stations). Delhi Junction and New Delhi Railway Station are now conveniently connected by Metro Line 2, just minutes apart, while Anand Vihar is served by Line 3. It will take about 40 min-1 hr to travel from the New Delhi Railway Station to the airport by car, depending on traffic.
Delhi Metro and rail network
The fast-growing Delhi Metro network provides a cheap, quick, hassle-free and air-conditioned way of zipping around the city.

Delhi Tourism has a "Hop On Hop Off (HOHO)" bus service, (Helpline) +91 11 4094 0000. A fleet of air conditioned low floored buses follow a pre-defined set of stops around the city and passengers can hop off the bus, see the place at one's own convenience and hop on the next bus.
