restaurant review #314 – Het Slachthuis is a vegan restaurant in Leiden (the Netherlands). We were here for lunch with friends a couple of months ago. ‘Slachthuis’ is the Dutch word for slaughterhouse, so that’s a peculiar name for a vegan restaurant! It is located a little bit outside of the city center, in a former flower/wheat factory, and cohouses with a communal sewing atelier.
