This week's choice goes to the café A (thanks for the suggestion). I've also read somewhere it is a nice place. But since it opens only at noon, this time we will have a lat(t)e coffee. So no more excuse like "it is to early..."
If you bring a gummy bear dressed and decorated, I'll buy you a cake (well the most beautiful is the winner).
Contengency plan: it seems to be a busy place, we can go to the ten belles café (other side of the canal) if we happen to lamely fail to enter.
