Microbuses and taxies from various parts of the Ferghana Valley go there. You can find those microbuses in near bazaars.
On foot or by taxie.
Amusement park - it is a really nice little amusement park. The carousels are of an old type, but that's the whole fun of it. It also features a disco, which is open during the day. There are also quite a lot cafes and an ice cream shop! Park looks really nice - green trees, some fountains. The carousels are cheap. Besides that there is a special circus performance free of charge. After each performance you can donate some money to the performers. It is very traditional and very interesting to see.
Certainly knives - there are knife merchants in the bazaar.
Also try out the various things in bazaar - there is this special sweet thing that looks like cheese, but it is hard to chew. It tastes nice and is cheaper than in Tashkent.
In the amusement park it is really worth to try some plov. The place is nice and you get to sit in these special outside eating ramps, traditional Uzbek thing.
