The currency in Prague is the Czech Crown (czk). Czech banknotes are issued in the following denominations: 100/200/500/1000/2000/5000. Some hotels, shops and restaurants accept Euros as well, but many only take Czech Crowns.As the official currency, the Czech crown is the best and often the only possible currency to use when paying. Although the Czech Republic is part of the European Union, the euro is not widely accepted here. Some stores, restaurants and hotels accept payments in euros but the exchange rate may not be very good.thanks
