Advertisement, a network that connects folks who want to cook for strangers with those who want to eat with strangers, is redefining the way food enthusiasts foster community around the dinner table. The concept is simple—hosts in any given city decide what and when they want to cook and how many guests they'd like. They post the information to the website, and interested attendees sign up. It's like an open-invitation supper club that offers a unique opportunity to share experiences and make new friends over thoughtfully prepared, home-cooked meals. The organization has established meal shares in more than 450 cities worldwide, from San Francisco to São Paulo, and founder Jay Savsani wants to expand the program to 10,000 cities in the next four to five years.
