I had the som tam Thai, the recommended chicken wings with fish sauce, sticky rice and a coconut smoothie (no sugar).
All were great and went well together. The only negatives were that they forgot my chicken until I reminded them when I had more than half finished my som tam. Also the som tam wasn't very spicy so next time I'll ask for more chillies.
The second time I got som tam Thai (no prawns, 1 chilli), chicken wings with garlic and sticky rice, all for 130B. The papaya salad is a big portion and is delicious but I think it needs 2 chillis.
