I got half a grilled chicken, papaya salad and sticky rice for 120B. Yum! The chilli sauce is great too. This is up there with the best of the som tum / chicken places.
The English menu only lists the full portion of chicken which is massive, so be sure to order a half if there's only one of you.
I think the ratio of the half chicken, papaya salad and sticky rice is just about right, so if you do order double chicken, you might also need double salad/rice.
They seem to give me the som tum without any chilli unless I ask for it and remember to ask for no shrimp if it's not to your tastes.
The local feel and smokiness adds to the atmosphere.
