Ukraine is a country of cash, so it is always best to pay cash. The local currency is the "Hryvnia" (abbreviation: UAH) which is divided into 100 Kopecks.
In 2004/05 new banknotes were put into circulation, but the various old ones are still valid and in circulation as well. This causes some confusion as you may have 2 or even more variations of the same banknote in your wallet.
In the last years the Ukrainian Hryvnia has been relatively stable. Nevertheless you might see some signs stating prices in US Dollar or Euro.
I usually prefer to get my money from cash points which can be found at almost every corner in Lviv. I really find it amazing how many banks you find in Ukrainian cities.
You can also exchange your local currency at one of teh many exchange booths. As their rates might vary, I recommend to campare a few rates and ask how many Hryvnia you really get for your currency. Just make sure that you don't have to pay a commission and that you count the money at the window in front of the person in charge.
Standards of public toilets in the Ukraine vary a lot. If you are lucky you might find clean and comfortable public toilets in bigger cities like Kiev or Lviv. But even here squat toilets can be seen quite often, also in older restaurants or hotels.
In more rural areas the situation gets even worse. Sometimes there are only holes in the floor or the doors can't be shut properly. Toilet paper is only provided by the lady at the entrance if you ask her. Be prepared that you will only get a few pieces of toilet paper, therefore it might be helpful to always have your own.
The use of public toilets costs between 0,50 UAH and 1,50 UAH, so make sure that you have some change available.
The best bet for a clean toilet is probably to go to a restaurant or cafe. Mc Donald's might be an
option as well ...
When travelling to a foreign country I always try to taste their local beers.
In the Ukraine the following two beers were among my favourites:
Chernihivske Beer is brewed by the Chernihiv Desna Brewery in Northern Ukraine. It is one of the best selling beer brands in the Ukraine. Nowadays they belong to the Sun InBev Company and produce 8 different beers, with their light beer being the most popular one.
Lvivske Beer is not only known in Lviv, but also all over the country. Rumours even say that it had the reputation of being the best beer in the former Soviet Union. The history of the Lviv based brewery dates back to the 15th century and nowadays it is owned by the Baltic Beverage Holding. At present they produce about 6 beer brands, mainly pilsner style ones.
Other well tasting Ukrainian beers which I tried are Obolon from Kiev and Slavutych from Zaporishzhia.
