Leon Restaurant

Leon is a London restaurant chain with dozens of locations and serves good fast food to take away or to eat on the spot. The location I visited was on Carnaby Street near Oxford Street. The menu is pretty diverse and has a lot of gluten-free or vegetarian options. All the food is made with organic ingredients...a fact which forms part of the company's "vision" which you can read about on the official website. Each menu item is marked and categorized as being vegetarian, gluten-free, or appropriate for a variety of food intolerances. The food is international so you'll be able to get some more exotic flavors if you like.
