Hi Albotross,

You will find most of information regarding the lifestyle in "begaluru".
Bangalore is a very nice place to stay (i stayed there for only 3 days, but i enjoyed and would want to visit sooooon
). As compared to other international business hub you might find lower standards of infrastructure (well thats nothing new, we in india can manage with everything and still get work done!!
).
But when it come's to social life. I can tell you its the best.
But you be there to experience the food , the night life and not to forget the real kind people i personally came across in bangalore. Unlike other south indian cities here language for me was not a concern.
Being from Mumbai, i tell you its a decent place to be with your family.
Good Luck and Best Wishes.
