The prices are good
This nice little restaurant is conveniently located. We came in around 20:30 and it was quite busy with mostly foreigners and a few locals; we could barely get a table.
We had fruit juices (quite ok), two main dishes and rice. (The large bowl for 20k VND is definitely more than enough for two people.) The sauteed sweet and sour pork was really tasty, although a bit sweeter than sour. The fried chicken Hmong King style is quite nice, but you may want some vegetables to go with it.
Service was nice and prompt. The prices are good.
