Going in a week or so, and wondering if the tea tasting is worth the time and tariff. In fact is the whole place worth the time and tariff.
The whole place: yes, absolutely.
The tea pairings: I never was a fan. The teas are, by far, the best Chinese teas to be had in Paris (until I open my own teahouse), but I think they'd be better off drunk on their own. The pairings don't always work, sometimes they do. If I went back I'd order wine with my meal.
We did the tea pairing last year and found it well worthwhile. How often do you get that option and it added to the fun of the experience. Personally I thought the tastes were interesting and enhanced the meal
