Actually, good question. There is actually nothing special about the place apart from the river, Prague castle, beautiful sunset, beer and and people hanging out there. But the place has a magic spirit, at least to me. I could go there every day in the summer.
If you wanna enjoy typical evening out of locals and expats living in Prague, dont miss Náplavka. You can go there only for a walk, or grab a beer, sit at the riverside and enjoy the view, sun and the moment itself.
Watching the sunset from here is just...awesome.
