Zagreb Eye viewpoint bar
Time Out says
The Zagreb Eye viewpoint, on the top floor of this iconic Skyscraper on the edge of the main square is the most beautiful way to see the city 360° and a nice spot for a drink at any time of day; from morning coffee to a glass of wine or two as dusk falls over the roof-tops below. Food is available all-day; as are free wi-fi and binoculars. Perfect for photography too.
