A member of staff prepares herself a crisp sandwich in the Simply Crispy sandwich cafe in Belfast, northern Ireland January 12, 2015. The sandwich shop which opened on Monday is the world's first crisp sandwich cafe, local media reported. The idea of a crisp sandwich cafe started as a joke article on a website called Ulster Fry. The hilarious piece poked fun at recent ridiculous foody trends like the cereal café that opened in London last year. What was once a satirical joke has now become reality, after Belfast cafe owner Andrew McMenamin decided to make it happen. Customers will be able to choose their bread and crisps and add cheese or ham to their sandwich, which will be served with soup and chips. (Photo by Cathal McNaughton/Reuters)
