Canned fish. Sometimes it's a necessity. That tuna fish isn't to become a tuna fish sandwich by itself, in other words. There are, however, some downright gourmet canned fish products that are miles away from the bespectacled Charlie the Tuna. One London restaurant is betting that foodies will pay premium prices for premium canned fish product.

The appropriately named Tincan doesn't even have a chef and very little by way of staff. Most of the dishes consist of canned fish with a variety of bread, greens and other simple sides. The restaurant only stocks the best of the best in its namesake, importing products from all over the world. Reviews have been positive, proving once again that fresh food is totally overrated (kidding.)

Unfortunately for can lovers, the restaurant is only a pop-up. It'll be gone in six months. However, if it remains popular the owners say they might consider something long term.
