Okay, you should know - since I didn't - this place is a co-working space, so you pay by the hour and all drinks and food are free.
I prefer it to Anticafe at Place Des Arts because even though Anticafe is cheaper and bigger, its cookies are dry and stale. This place has nicer food.
However you should also know that this place is SUPER QUIET. It's not somewhere to go in a group or with a friend; it's for working and whispering only!
