After returning from Thailand we were craving some authentic Thai food which is quite hard to find but Khao San Road hit all the right taste buds!
My only complaint would be that we felt rushed.
Within 15 minutes of having our plates cleared when we were done eating, we were asked if we would like anything else, if we would like our bill, and then if we were ready to pay our bill. I understand that due to the small space and long line it is inconvenient to have people sitting for hours but enjoying conversation with friends is part of the pleasure of eating out which we couldn't do once we were done.
