HDFC BANK for me is trustworthy bank and I am associated with this bank since 2012, found it very helpful and comes with great features. Minimum maintaing balance is low, ATM are available in huge number and everyone will agree with me for this . Internet banking is so smooth and they are available at a single phone call satisfy with customer service. FOREX rates are tooo low last time I visited abroad and used hdfc forex and charges are quote low which help me to save my money as well.
