After breakfast, wander over to the stunning Grand Place, Brussels' central square, where you can admire the 17th-century guildhalls and the Town Hall.
If your timing is right (every two years in August), catch the spectacular Flower Carpet in the Grand Place, or enjoy the beautiful floral arrangements in the surrounding gardens.
End your day with a casual dinner at Fritland, known for serving some of the best fries in Brussels that'll cater to both adult and kid-friendly tastes.
