A lot of people spend their time on Khao San road but it is not a true representation of Bangkok. Pick up a local free listings magazine and try some of the bars the Thais go to. There are plenty of nice restaurants and bars around Silom and Sukhumvit roads.
BTS Saladeng for Silom or BTS Nana, Asok or Phrom Phong for Sukhumvit.
