There are several Tibetan teahouses around town where you can grab a cheap cup of changamo(sweet tea). Most are grungy Tibetan only places, blasted by high-decibel kungfu videos, but there are a few exceptions. The best places are the Turquoise Dragon Teahouse,a Tibetan-style place with a fine balcony overlooking Dekyi Shar Lam, the teahouse underneath the Tashi Targyel Hotel and the pleasant teahouses around the ponds to the east of Potala Square.
