"For the sleepy 16th arrondissement, Substance is a refreshing jolt right from the door. Expect a relaxed, but exacting, foodie crowd in the evenings; these are diners who are either well-versed in chef Matthias Marc's resume (a Top Chef candidate), champagne connoisseurs, or locals of Western Paris. The biggest draw here is the champagne selection, with more than 180 cuvées from both well-known houses and small producers; Substance, named for a top-end bubbly, is the only restaurant in Paris serving the Jacques Selosse Initial Brut cuvée. For food, you might find potato emulsions with trout eggs and pickled onions, goat cheese and beetroot cannelloni, and lots of plant-based dishes (be sure to specify any food allergies or intolerances right when you get the menu). From start to finish, dishes are refined and modern, predicated on the seasonality and local-sourcing that diners have come to expect from the best French restaurants." - Sara Lieberman, Lindsey Tramuta
