Catching up on a lunch or a dinner, or any breakfast or high tea is not necessarily to only satisfy physiological requirements. In fact, people often socialize during meal times. "Catching up" is what we generally know it as.

There are restaurants and cafeterias in every nook and corner of the world. Some are casual, while the others are fine dining and luxury personified. Some serve meals by the alleyway, some in a cart. Beachside cafes to lagoon bars, food can be served any place that is hygienic and clean. It is not a difficult feat.

But, for those adventurous souls out there, there are places in the world, which are downright unusual and quirky to call it best.

Following are some of the most unusual hangout and dining zones in the world.

Irrespective of the cuisine, people love to try out new places and different ambience. Going out often takes us away from our realities and gives a much-needed break. Many Restaurants in Dageradplaats and restaurants in Zurenborg provide a different ambience and an easy place to chill and hangout. The Aan Het Strand Van Oostende is one such restaurant, which believes that reality is what we have and fantasy, is what we need.
