After seven days in Delhi it was wonderful getting back to the Bombay. The two cities are so different... I love the spirit of Bombay, it was refreshing to see one of the Auto rickshaw (Tuk Tuk) drivers, refusing to take money from me, as I had helped him start his Rickshaw by pushing it all by myself (although I refused to accept his gesture). Where as in Delhi the Auto/cab guy would refuse to take you to certain parts of town and would never use the electronic fare meter (he would just give any random number that would come to his mind). Some small things that differentiates the two cities.
On the other hand the food in Delhi is way better than Bombay, even the street food in Delhi is lot better than most established outlets in Bombay. So if you are a foodie and love Indian food (Veg and Non-veg, esp. Mugali), Delhi is the place.
