I keep hearing that support local restaurants contributes to sustainability, but. . HOW. Do you know what I found? Support local restaurants is sustainable when the food that is served up is grown or raised by local producers. (The definition of "local" varies, but most agree that is produced with a range of 150 miles to be "local".) Restaurants are most likely to participate in the local food movement are independent institutions to local capital . Patronage corporate chain restaurants that are geographically "local", but receive their food by truck sites remote distribution is not considered "eating local" – as the previous poster said. Independent restaurants, local businesses who take pleasure in serving local food often go more to support the local economy. They can buy works by local artists, using local designers and printers for menus and advertising, and so on.
