Chiang Rai cuisine is predominantly Thai and the food here is both excellent and cheap.
The food court next to the Night Bazaar is a great place to go to choose from a whole raft of local dishes. The court has two sides where kitchen after kitchen has a menu on boards above the counter, most of which are in Thai and English. Like all food courts you can take one dish from one place and something else from another. Try some kebabs with a chicken rice and basil. It may blow you away (spicy) but for 50B all in, it's got to be worth a try. Regional dishes include roasted pig intestines and naturally most dishes come with sticky rice. At each end of the court are counters selling water, beer and soft drinks. Most nights, but especially Saturday, Thai music and dancing are performed on the very grand stage. It's all free and no one comes round asking for money . The food court is a great way to start the evening without hurting your wallet.
