Food and beverage are the foundation of a destination's sense of place. Visitors come to your area for the great food and drink that your area is known for. Food lovers aren't coming for chain coffee or hamburgers. Food lovers are some of the most engaged and interactive consumers available. If we love a product, not only will we tell everyone about it, but we'll also find out how to acquire it back home, even in another country. We also love shopping for food - not just to eat while visiting but to take home as souvenirs and gifts as well. It's not uncommon to literally fill empty suitcases with food and drink products we want to bring home. Our experience with your local food and beverage products while we are visiting your area starts the word-of-mouth engine - the most effective kind of promotion.
In the short term, your benefit is incrementally more food and beverage products purchased and consumed. In the long term, your benefit is exponentially more food and beverage products purchased and exported. In both situations, you're selling more product and earning more profit.
