David Lebovitz says, "Here's my address book for the most popular, and my favorite places for ice cream in Paris," and proceeds to list six top glaciers and what he likes to order at each, plus the names and addresses of four more he's heard about but has yet to try. There's possibly no one else whose opinion on this I'd trust more, as he lives in Paris, is the author of the cookbook Perfect Scoop, and his recipe for Salted Butter Caramel Ice Cream is supposed to be better than that of Berthillon, which is regarded as the best ice cream maker in the world. Consider it a list you must print out when visiting Paris!
(The strawberry basil sorbet that you see in Robyn's photo above is from Dammans in the 5th, which Lebovitz describes as a "tiny little corner shop is where you'll find a few unusual flavors amongst the familiar. There might be Argan Oil Ice Cream, made from the Moroccan drupes themselves. As well as caramel, a tropically-tinged mango sorbet or simply rich boule of Vanilla Ice Cream. All of which can be enjoying outdoors overlooking the Seine, just a short walk from Notre Dame.")
