Everything from the menu is good and their potato & leek soup is the bomb!
Don't go there if you are on a rush, it will take usually 20 mins for food. And I'm serious.
My favs are as below:
Quiche (all of them)
Prosciutto sandwiches
Moroccan grilled sandwiches
The gerson (juice)
Soups, especially the veg one they are really good
