A typical Kyrgyz meal will feature starchy foods like bread, rice, and potatoes, usually centered around some sort of meat, usually lamb, mutton or beef or even sometimes horse meat. Some of the more popular staples are plov, a Central Asian dish consisting of a bed of rice cooked in oil, topped with lamb or mutton, shredded carrots, and occasionally whole garlic cloves. Shashlyk, a marinated and grilled lamb, mutton or beef kebab, is popular all over the former Soviet Union and is typically eaten with bread, raw onion slices, a voluminous amount of vodka. Samsas, much like the Indian samosa, are available at roadside stands across the city. Usually these are cooked in a tandoor oven as a puff-baked pastry and filled with onions, mutton and mutton fat.
The national dish of Kyrgyzstan is called besh barmak (literally: five fingers, because the dish is eaten with one's hands). It usually consists of horse meat, although sometimes mutton or beef is substituted in, that has been boiled and served mixed with homemade noodles. A sheep's head is usually served along side it. If you can land an invitation to a wedding in Bishkek, you'll most likely get a chance to eat besh barmak, although you can also find it are traditional restaurants.
Russian dishes are also fairly ubiquitous in Bishkek because of the large number of ethnic Russians who still live in the city. There are a also growing number of restaurants and cafes catering to more varied tastes.
Uyghur food is popular and fit the taste of many westerners as well as locals. E.g. the chain Arzu have a few restaurants.
