Last year I went on a trip to Belgium. Great place to visit, not only because of nice places such as Gent, Brussels or Brugge, but because you can enjoy a wide variety of beer, fries and waffles.
You will find plenty of places to enjoy waffles. However, while visiting Brugge, we stopped by at Otto waffle and enjoyed their delicious waffles.
If you are planning to visit Brugge, this place is worth visiting. I leave you a link to their website.
