You might have read about Plateculture as it was hailed as 'Airbnb for foodies' right after its launch. The premise might sound a bit menacing – using the app (currently web-based) you can basically book yourself a home-cooked dinner – and then go and eat it in someone's home. But approaching it like that, Airbnb is just as creepy. The developers call it 'secret social dining', and there are now 32 countries to choose from. Some have been saying that it's great for discovering new cultures when travelling (the list of countries includes Vietnam, Hong Kong and Peru), but it is also just as good for experiencing new food at home (UK, Latvia and Lithuania and other European countries are also in the list). You can also register as a 'chef' and receive hungry visitors yourself.
