This restaurant, on the Petite France side of town, has a compelling and creative menu of organic vegetarian dishes. Look past the boring location (it has no real view to speak of) for great food at a moderate price.
In late August 2008, the owners opened another restaurant, Bristrot et Chocolat, which, although I haven't tried it, looks fantastic. It's located on Rue de la Râpe, near the Cathédrale de Notre Dame.
