Time Out says
Z am Park was the first hip café at this end of town. It's now been joined by several others, but that means you'll be able to get a table at this lovely venue.
It was the first hip café to open at this end of town, and for a while even the cool and classy from the other end of Zurich travelled here to see and be seen. With half a dozen other places now open in the area, the hype has definitely cooled down, but that is much to the benefit of this lovely café - mostly because you can now travel here all the way from the other side of town and actually get a table. Sit outside to watch to world go by or inside on one of the custom made chairs.
