I am basically a Bombayite but of all the cities in India I have frequented Bangalore the most. A few years back I was posted to Bangalore for about 1 month and I stayed near Brigade Road.
As a person from Mumbai I find Bangalore life very slow. No jostling around (Oh I missed the Mumbai local trains), no crowds (how I missed the maddening crowd of VT/Churchgate station). Though it is a very becoming city it still lacks the sophistication and character of Mumbai.
Having said that I enjoyed Bangalore. The Brigade Road, MG Road can be called modern. Big shopping Malls, Pubs and Restaurants gives the city a modern facade. The restaurants and the type of eateries were fascinating.
For the IT savvy young person this is the happening city. You find lots of young rich people. It was to be the city of the pensioners is now also the city of the young, techno savvy individual.
