Split is becoming like that as well. Right now, almost all of the restaurants and bars in the center are closed until next season. It's all a big ruse.
Split seemed like a trashy euro nightclub scene for us. We much preferred Zadar, which was totally chill and reminded me of Key West with it's artsy, laid back vibe. Skradin was also amazing- I want to go back there with nothing to do for a month and decompress and write a book.
Want to walk around the city walls? That'll be €20! And if over-priced, mediocre restaurants are your thing, there's plenty of them too.
