The cafe is free to enter even if you aren't going to an exhibition. The woman who took our order was friendly and patient, while the man who brought it to our table was efficient and charming. The environment is tranquil (we sat in the...cloisters) and tables are nicely spaced out. Food was on the pricey side, but the quality and presentation is high standard. 15 euros for a mozarella and tomato baguette (actually 3 mini baguettes) and 7 euros for a small selection of tempura vegetables). We just had these few snacks and coffees, but I wish we had stayed for longer and had a proper full lunch to take advantage of the lovely setting and obvious quality food. (Although the menu is short.)More
