M&M's World

With its four floors and approximately 3,250 square meters, this is the largest candy store in the world. Despite M&M's being the biggest chocolate selling brand in the world, this store is the only M&M's World in Europe. It was opened to the public in 2011 and the majority of the store is taken up by the store's merchandise, such as T-shirts, soft toys, M&M's characters and much more.

But of course, the main draw of the store are the world-renowned M&M candies filled in plastic boxes of every shape and size imaginable. So if you are a fan of sweets, be sure to check this one out.
