Last year was Lev only. Get ya money changed up before you go, OR use ATM to get Lev, OR change at hotel/proper bureaux de change - DONT USE THE GUY ON THE STREET! you will be ripped off/given fake notes etc!
getting money from ATM is best! Some exchange offices can rip u off as well if you don't read the signs carefully. Officially only LEVs are accepted. Even if some places accept Euro, the rate might not be good.
