Is Prague expensive for tourists?
While Prague is more expensive than other Czech cities at an average cost of €50 to €80 per person per day, it is certainly more affordable than other Western European cities if you're travelling on a mid-range budget.
Is food and drink expensive in Prague?
For most of the tourists (I mean especially western Europeans, US) Prague should be cheaper (probably much cheaper) than at home. But be careful, there are many places where they want your money and don't shy to ask for two or three times higher prices than is common.
Is Prague safe at night?
Aside from property crime, Prague is a relatively safe city. The rate of violent crime is low and most areas of Prague are safe to walk around even after dark. Be careful on Wenceslas Square. It is usually packed with tourists and the crowds make things easy for pickpockets.
