Before leaving London, a friend who studied in Cologne recommended a visit to cafe bar institution - Hallmackenreuther.

The bar is rumoured to be furnished with the original furniture from Cologne Airport, so we expected to see lots of '50s and '60s classics of German design but...it wasn't so. For the duration of the festival, the vintage furniture has been replaced with the experimental 'Workshop' series by Jerszy Seymour -- a curious collection of coat stands, armchairs, bar stools and table, with structures built from common wooden batons joined together with an unusually hard-curing wax. Although they look fragile, the pieces are standing up well to the heavy parties the bar is famous for and will remain a functional part of the interior until the end of the festival on Monday.
