I have never come across one of these in the city? Does anyone know where one may be hiding?
Try one of the Guapa juice bars. Here's an address for you
GUAPA LOUISEChaussée de Vleurgat 1421050 Bruxelles (Louise/Châtelain)Du lundi au vendredi de 7h à 19hLe samedi de 9h à 19h
yeah they're really great. I first discovered them when they opened the one in City2 (on the lower floor near the escalator).
I've heard there's another one located in the Central Station area - but I've actually never seen it.
oh and i just found their leaflet online so here it is :http://www.guapajuice.com/JuiceMenu.pdf
