Home to some of the most famous (and oldest) colleges of India, North Delhi is awash with students and, consequently, cheap eateries. Street food is the name of the game here and tiny kiosks serve scrumptious snacks all around Delhi University's 'North Campus'. After you've had your fill of chhola bhatura or chaat, go for a walk on the Ridge, a protected forest area, also called the lungs of Delhi; then head to the wholesale market of Karol Bagh offering everything from sarees to sindoor to slippers.
