Blend Hamburger Madeleine is a burger shop on the luxury brand street in Paris, serving a signature burger and sweet potato fries. The signature burger has a juicy patty and a soft, castella-like bun, and the sweet potato fries come with mayo or garlic sauce. When eating in, you order from the second-floor seating area, and the upper floor has ample seats and a clean restroom. The burger is on the salty side.
