Le Grenier de Notre-Dame is a vegetarian restaurant two steps from Notre-Dame Cathedral, serving vegetarian and vegan menus in the historic district of Paris. It offers vegetarian burgers, pasta, and lasagna, along with vegan and gluten-free options, organic food, and specialty beers. The downstairs seating area has plants and quiet music, set apart from street and shop noise, and the dishes come out with vivid colors and generous portions. Prices overall are high enough that a casual stop is a strain.
