There’s not a great deal to choose from. If you’re staying with a family in the homestay programme, then you can take your meals with them, which they will prepare. Breakfast is $2, and will most likely be a soup, or pork and rice. Lunch and dinner are $4, and may be fish or pork with vegetables and rice.
In the village adjacent to the temple, there is a busy restaurant which serves up perfectly good local food for $2 to $3 a plate, including rice, noodles and soups. Most importantly, they also have iced coffee with sweet milk for 75c.
