Tchibo is a German institution: they started after the war selling bad coffee and opened expresso bars all around the country, then started selling widgets. Now they are primarily a widget company, selling "Jede Woche eine neue Welt", each week a new batch of themed, good quality stuff. Most is tacky but some is very good design and moderately priced. Small Tchibo shops/coffee bars are everywhere. Tchibo Prozente is their network of large sales shops. You never know what you'll find.
