The advantages of organic food are many. It tastes better, it is of better quality, and since the food is grown without pesticides or fertilizers, reliance on petroleum products is reduced. When purchased locally, you support the local economy, too. Serving organic food benefits your image because it shows you care.
The better taste of organic food comes from letting it mature "on the vine", rather than being forced to ripen with gases. Organic foods grow in soil that's nourished with compost, rich in nutrients and organic matter, and that soil nourishment benefits the plants. If raised and grown locally, the shorter time between harvest and plate means the food tastes better and is more nutritious.
When you show you care by providing the best tasting, best quality food, your guests recognize that and appreciate it. When people know they matter, they respond with return visits and referrals, and that's the best way to keep your business strong and growing.
