I went there today for their Groupon deal, an afternoon tea. It was nice to have an afternoon tea…read morewith an Asian twist. It started with some small dishes dim sum style. While they paired it with 2 different teas: Oolong Ginseng and a mixed black tea (I think) with rose buds. Then it ended with a selection of their chocolate truffles. They're quite delicious. Het Zesde Geluk is a very interesting workshop center where they cater to a group of people to educate them about food and tea. I love it!!!! Pros: - super friendly service - interesting and great products - eclectic selections on cooking workshops - probably the only place in Rotterdam that knows about real tea culture (not those flavored tea craps most people drink) - good selection of tea sets to start your tea drinking/brewing hobby Cons: - I wish they're open as a normal cafe, I'd go there frequently.
