For restaurants, e-commerce means additional revenue from your existing customers or from new customers. By selling merch, speciality menu items, gourmet ingredients, or drinks (wine, cocktail kits, craft beers, etc.), for instance, you give customers the chance to bring what they love about your brand into their own home.
You can also use e-commerce to streamline your online ordering process and expand accessibility: through your online store, customers can conveniently place orders for curbside pickup, takeout, or delivery. You can even sell creative items like a happy-birthday call from the chef, an autographed cookbook, or a membership.
