Bath & Barley is a beer spa a step from the Grand-Place, where guests soak in handmade oak tubs filled with warm water, yeast, hop and malt. Every room is private, seating up to six, and the Monk experience adds a hops-aroma sauna at 70°C and an oak barrel to cool down in. An hour for two starts at 139 euros, or 169 euros with the sauna. It opens daily, from 11:00 on Saturdays and later on weekdays.
