Heavenly Desserts Marylebone is a dessert shop in Marylebone, London, serving waffles, crepes and milkshakes. Its signature items are the Biscoff American waffle and milkshakes, and the waffles are crisp outside and soft inside. It stays open late enough to visit after a show at Regent's Park Theatre, and food comes out warm and quickly. Inside, the room smells of vanilla and warm cookies.
