Rotterdam - Poffertjes
Poffertjes are small pancakes and a Dutch speciality. Traditionally serverd with a piece of butter on top and covered in sugar. They are filling enough to count as a full meal.
If you are around the market place, then you should probably step by the Poffertjessalon Seth. It's located in Hoogstraat 177 and serves delicious little Dutch pancakes.
You can even watch the bakery man make them.
A must-go if you are around the market place!
