The most interesting place to go to look for things is the black market, called naranthul zach. The minibusses leave on the main street on the ither side of the suchbaatrsquare at teh busstation.... just wait for the small busses and the man in the bus shoutig zach, zach, zach.... it's 200 or 300 Tugrik to get there. Entrance to the market is 50 Tugrik. You can find everything at this market.... also old nails, things to built a ger (jurte), clothes, teapots, whatever... . the market opens at 10 a.m.and closes at 6 p.m. .... but it's not worse to go before 11 a.m. if you're just interested in buying and not seeing how the people bring the suff and build up everything. the market is closed on tuesdays.
Becarefull for your money! Especially at the weekend, when it's stucked with people! Realy, you wouldn't be the first person loosing the money purse...... so just take a bit of money and the best is, but it in your pocket and your hand around it!!
A part with very expensive shops and a lot of stuff is also if you go out the west entrance of the Gandan Tempel to the next area, there is a big and very modern shopping street!
