Unique!
A unique place in Brussels with an unbelievable atmosphere based on both times I visited the place.
Postive : the huge couches to lay on, the atmosphere, the smoking permission (until now), the French music (Edith Piaf, Jacques Brel), the many rooms, the strawberry-flavored wine.
Negative : no coffee or tea is served as well as only a few beers are served. The bar is specialised in flavored teas (that are quite sweet like juices) and a special drink with violet (but again way too sweet for my taste).
Result : you must see this place!
