Café Boudin operates as a small vegetarian cafe with a rotating weekly menu that includes tofu bahn mi sandwiches, vegan pastries like pistachio babka, and seasonal vegetable dishes. Known for its excellent filter coffee and chai lattes, the cafe attracts visitors for breakfast, brunch, and light lunch in a relaxed setting near Brussels' Museum of Fine Arts and central station—with outdoor seating available when the weather permits. Prices lean toward the higher side, reflecting the upscale neighborhood, although some guests find portions modest for the cost.
