HDFC is a really good banking service. I have an account with hdfc since four years now and their services are really good. My first company was only tied up with them so I had to opt for hdfc, back then everybody said hdfc is a bad bank . But I must say its an excellent bank with amazing online portals that are just so reliable and also good interest rates when it comes to product EMIS. Its pretty reasonable.
Must try banking service. The ATM service as well is really good and is in abundance in most areas.
