Newlyweds Josh and Alissa were at a party and received a challenge that shook them to the core: Do you think you can really make a difference? Especially in a place like Rwanda, where the scars of genocide linger and poverty is rampant? While Josh worked hard bringing food and health care to the country's rural villages, Alissa was determined to put their foodie expertise to work. The couple opened Heaven, a gourmet restaurant overlooking Kigali, which became an instant success.
