When I was there, at olympic park I could get a huge tastey lunch for 2-3 dollars. A cup of tea would be about 30 cents and a main course portion would be a dollar. Clothes are really expensive though. I bought one of hte official olympic shirts and it was $80, no matter where I went clothes were always expensive. Vodka was dirt cheap too, about 70 cents a liter, but the homemade stuff was even cheaper. Bus cost 50 cents to ride. Taxi's are expensive if they think you are a foreigner, I would often get a local to order a taxi for me, it would be much cheaper.
