Time Out says
Zürcher Brockenhaus is an upscale second hand shop with lots of great finds to make from books, classic furniture and design objects. There's a café bar, too.
Parts of it might remind you of a fancy vintage design store - and the prices are definitely not flea market - but there is always a great find to make at this upscale second hand shop with its several floors and special corners for books, classic furniture and design objects. It takes time to get a clear picture of all there is to see, so you might want to stop and sit down for a while - good to know that this second hand department store comes with its own café bar.
