Small shops downtown provide typical Tibetan clothing and jewelery and accessories bought by the herdsmen and nomads frequenting the town. Look out for stores selling antiques. On the road leading north from the bus station, you'll find several shops catering for monk's outfits and religious artifacts, as well as selling the beautiful curtains adorning windows and doors in that region. There are even shops selling traditional Tibetan hand-carved furniture.
Supermarkets on main-street sell food and toiletries, you can also buy bottles of beer and decent Chinese wine to make up your own nightlife.
