HSBC's virtual bank first direct has launched an online social network for customers to post and view recommendations of local attractions.
The Little Black Book site lets the bank's UK customers share reviews of anything from shops to restaurants to art galleries to festivals.
The reviews are accompanied by a Google map and customers can enter their postcode to find recommendations in the area.
Designed by digital agency MadeByP, the site is being made available to all UK customers after a trial involving 20,000 users.
