Re: what about the revisioning of bars?

ah ah! none of these things of course exist in bars, even in the great Berlin, a part from a bottled kombucha that you would probably find a blasphemy.
I think you could have great success here if you happened to open a bar, making white tea drinkers blush for lack of original thinking, not that there's anyone too judgemental, people are very easy going here, thankfully, so no blushing.

On another note, it seems I know the grand-daughter of Mr Kir, which was great surprise, you never think you would possibly meet someone like that, with a cocktail name. And this gives me the authority to be the extra-picky: when it's made with white wine it's called kir, when it's made with champagne it's called kir royale. I never thought I'd ever really use this piece of information, ah ah! in honor of the chef in you.
