This restaurant is located very near Khao San Road, but it's not a restaurant that you will generally pass. Look up the address first and you have to turn off a main road down a back alley to find the place.
The food was delicious. We ordered pumpkin hummous, massaman curry, thai green curry, and red rice amongst other things. It's shame we were only in Bangkok for a few nights because we would have loved to go back.
The service was good, and the whole meal with greens was very cheap.
Available to buy at the restaurant are cookery books, sauces etc.
