Budapest is the capital of Hungary (honest). Hungary is a part of the EU (which Hungarians are undoubtedly proud of, because of the number of EU flags hung out everywhere). But it isn’t part of eurozone, which was a complete surprise for me. They have their own currency called forint, and you exchange it at the rate of one kilo 260 for one euro. Because of that, you usually count them in thousands (1000 HUF ≈ 4 EUR).
