Nightlife in Sanya is centered along Dadonghai Beach and Time Coast Bar Street. Most of the action is on Yuhai Lu, where there are rows of seafood restaurants and beachside bars. Some of the beachside hotels have barbecues and various types of musical performances (both Western and Chinese).
Food-wise, Sanya’s most atmospheric and fun eating option turns out to be its cheapest. As the sun goes down locals set up makeshift BBQ restaurants in the streets surrounding the beaches and markets. Simply find yourself a table and then buy what you want from any of the vast number of food stalls and wok wagons assembled by the locals. A delicious and complete meal for one can be had for Rmb15-20. A large bottle of cold beer (from the corner shop) should cost around Rmb4-6.
