This is my favorite place in the city. Across from a museum and among galleries (including itself), it serves delicious Illy coffee (same as I drink at home), has healthy eating options in the form of savory crepes, and desserts, and great teas. The prices are a bit high but I'm pretty sure it's justified by looking at their ingredients...you really are paying for quality here. The space is nicely laid out, brightly lit, there is free wi-fi, it's open till 10pm or 11pm every night, and it's on the way home from school/work. I come here several times a week and know the people who work here by name.
The service here is admittedly not great (okay, it's plain bad) and that costs it one star. If you order a crepe and you want water with that then you'd better ask for water else you won't get it. Same for refills. If you finish your meal don't expect them to take the empty plate from your table. If you order a drink then you'll probably have to ask for a napkin. If you order an Americano then you have to explain how you want it because the thing they'll bring out otherwise is NOT an Americano. The people here are really very friendly and nice, they're just not service oriented and are too busy cooking to be attentive to customers in the dining area. If you just ask they'll be happy to provide whatever you need.
