I've been to Khao San Road at least 5 times since they opened, and was a huge fan. This is, until they became so in-demand that all service standards went out the window. The bathrooms are dirty, the restaurant is getting beat up, and the staff are less than helpful. I am OK with waiting an hour for great food, but the service better be on par. While we waited for our food on the last occasion, we saw tables sitting empty for over 10 minutes. I imagine this is because they don't have enough staff to clean the tables and turn them over. Also, they waited until the end of our meal to tell us that their credit/debit machine wasn't working, and told us that we'd have to find cash at a nearby bank machine to pay. Not a sorry, not a thank you, and no compensation what so ever for the inconvenience. In fact, we got a "it's not our fault". It's really too bad, because the food is fantastic. If they can get their act together I might go back one day, but not anytime soon, and I would suggest that if you don't need to "be seen", there are other places with food just as good.
