The Distance From A to Z is a bit of a love letter to Paris -- even though none of the novel takes place in Paris (kind of makes it easier that way, you don't need to deal with reality). But one of my favorite spots in Paris is the Angelina Cafe.
Truthfully, I don't really know what it's like anymore. The Angelina I remember is from when I went when I was 14 on a family trip. It was the most opulent place I'd ever been and the hot chocolate was this thick creamy wonderousness that came out of a teapot right into your gold-rimmed tea cup. It was heaven in chocolate and like Zeke and Abby, I hope to visit it again one day soon.
