My husband proposed to me in Prague in 2008.
Maybe there have been a lot of changes since then, but two things that I'll never forget are, the architectural creativity in the use of small spaces (bars, restaurants/cafes, elevators, and showers). The hotel that I stayed at had the tiniest elevator I had ever seen :)
Secondly, the dumplings - Beef Goulash and dumplings were amazing. The dumplings were stuffed with herbs, something I had never thought about doing before. I have never made plain, boring dumplings ever since then:))))
