Dinner at a Persian restaurant called Teheran; pubs are not the first association I have with Teheran, so I assumed anywhere with so unprepossessing a name survived on its food. Fantastic buttery chicken and lamb kebabs. Then met up in Altona with a couple of people I'd met in the conference in Vienna last month - they have solved the crystal they've been stuck on for two years, thanks to chemistry rather than any particular contribution from the workshop, so we happily drank wine together.
I've just reached Copenhagen after spending the day in Lübeck. Hansestädter are almost too easily photogenic on clear days: blue sky, red brick, green copper roofs, water. Lübeck has particularly good spires, and a Great Gate the right side of which is leaning into the swamp in which it was built and containing a nicely Hanseatical exhibition (apparently Boston in Lincolnshire is England's main Hansestadt, where in the 1200s we swapped wool for salt cod).
I do not recommend anyone to drink bubble-tea in Germany until it's caught on a bit more. Eew, raw tapioca.
