You must try roselemonade. Nice ambient, unfriendly (hot) staff, expensive and it's hard to catch a free sitting place. They have nargillas, good bathroom for selfies and great location. I love it.
Perfect for friday night out. I adore music they play, some remixes of famouse songs. They don't play folks or "cajke" and other shitty Balkan music. That makes them kind of classy and unique in Zg.
