I have a relative doing something with restaurants. Made some iOS app/ website and put pictures, 1-2 line reviews there and on sites like FB, instagram etc. With about couple of months of effort, he was able to mooch off 1000s of restaurant meals along with dozen of friends and family members. His total vocabulary about food is 'amazing', 'awesome', 'tasty', 'yummy' when using with spellcheck of course.
