Singel 404 is not just an ordinary address on the Singel. It is so much more. Singel 404 is a cozy, canal-side café well known for its delicious, affordable sandwiches. The restaurant offers a variety of hearty breads and practically every sandwich topping imaginable. The combinations are heavenly. If you still have some room at the end of the meal, make sure to order a piece of cake (or come back later). You will leave stuffed yet satisfied and ready to conquer the rest of your day. The restaurant has two levels, but it still is a bit small. You may have to wait for a table, but it is definitely worth the wait.
