A small bar directly behind the cathedral, distinguished by the most chaotic collection of religious statuary in Belgium — every available wall and shelf is covered in plaster saints, virgins, crucifixes, candles, and chasubles. The name means "The Eleventh Commandment" and the joke is on the décor.
The drinks are standard Belgian — Westmalle, Duvel, De Koninck, jenever — and the prices are tourist-friendly because of the location. The interior is the reason to come. Best at sunset when light comes through the small windows and lights up the statues.
