This is a partial list of my favorite places to eat in the Washington, D.C. area. All of these restaurants are vegan-friendly; it is possible to order a meal at these establishments without any animal products (meat, dairy, eggs, fish, etc.)

Busboys and Poets
This is where you might find me on a typical Saturday night. Both vegans and die-hard carnivores can find tasty food here; I particularly enjoy the Vegan Cobb salad and the Vegan Calzone. They also serve brunch, with a good tofu scramble and breakfast burrito. There are multiple locations in the DC area, but I go to the Arlington location most often.

Sticky Fingers Bakery
If you have ever wondered how you were going to cook a vegan birthday cake or a dairy-free wedding cake, you could just leave the baking to Sticky Fingers. They offer vegan baked goods, with a smattering of gluten free offerings, and a short menu of vegan deli food and takeout offerings. Their sticky buns alone would be enough to keep their neighbors coming back for more. A visit to Sticky Fingers is now mandatory whenever I head into that part of the city.

Sunflower Vegetarian Restaurant
Sunflower is an all-vegetarian restaurant, part of a global Taiwanese chain. A meal at Sunflower is a good way to introduce people not familiar with vegetarian or vegan diets to the variety and succulence possible without involving meat. The menu varies from noodle soups, pasta, and Indian-inspired curries to vegetable sushi and entrees made with sauteed vegetables, tofu and wheat gluten. Brown rice comes with most dishes.
