Location And Boundaries
Ukraine is located in East-Europe plain. The most part of the country is in low-lying lands, fertile plains (steppes) with two highland areas: in the South -Crimean Mountains (the highest point: mt. Ramantkosh, 1,545 meters) and in the West - Carpathian Mountains (the highest point: mt. Hoverla, 2,061 meters). Southern coast of Ukraine is washed by the Black and Azov Sea, coast line is 2,782 km. The majority of Ukrainian rivers flow into the Black Sea, among the biggest are Dnipro, Dnister, Danube, Desna, Pivdenyj (Southern) Booh. Natural resources: iron ore, coal, manganese, natural gas, oil, salt, sulfur, graphite, titanium, magnesium, kaolin, nickel, mercury, timber and arable land.

Food & Water
You will be impressed with quantity and quality of restaurants - national Ukrainian cuisine, European entrees, Italian Pizzerias or just fast food. Medium-range restaurants have affordable prices even for a traveler of modest means. Ukrainian cuisine becomes more and more popular with its traditional Borsch - tomato red and sorrel green; several kinds of Ukrainian Vareniki (dumplings) stuffed with all kinds of meat, cheese, potatoes with mushrooms; Golubtsy (cabbage rolls) - cabbage leaves with mixture of rice, meat, carrot and fried onion inside, these are usually served with sour-cream; jellied meat with horse-radish; suckling pig; delicious stuffed fish and plenty of other Ukrainian specialties. We do not recommend drinking tap water. Use bottled water instead, even to brush your teeth. 
Electricity
The standard electricity supply in Ukraine is 220V/ 50 Hz. Ukrainian plugs are of the same type as the most European countries have - two round pins. If electric appliances you bring have different specs, make sure to pick-up a converter and/or plug adapter.

You can identify such places by credit cards signs on the entrance door or by the cashiers raw.

This document might be useful when going through the customs upon departure from Ukraine.
