I recommend all the sapai dishes but not the tom yum soup. It seems they set prices as they wish for veggie which shouldn't be the case.Understandable if it were for crustaceans as they are price/kg.
Update 2023: The service has gone down considerably. Especially if you go to the new annex. Don’t get me wrong, the food is still delicious but the staff… I prefer the older original building.
