Restaurant de Waag Leiden I like combo of long & cafe tables. I would put the cafe tables (single work stations) in the space as you first walk in. The long table(s) in that room with the angled gass window.
The Old Harbour was once the place where the river Rotte flowed into the Nieuwe Maas, before the dam that would give Rotterdam it's name was built. Today it is a popular nightlife destination and there are many historic ships in the basin.
