I went to the take-away waffles stall outside, and found them delicious and fairly priced (2,80€), especially for being in the centre of a very touristy area. The waffles are true to Belgian style, relatively dense and made with pearl sugar, so they've got a lovely crunch! They make them fresh in front of you, which is great because you'll get a nice hot one. DON'T bother with extra toppings (get some cream if you really must), but as always, Belgian waffles are best alone. All the other stuff added isn't a Belgian waffle, it's a tourist waffle, and not worth the price. And yes, it's cash only; welcome to Europe!
