Turn failing malls into all restaurants. Big brands, local Mom/Pops, etc. Organize randomly or according to cuisine (steakhouse, seafood, desserts, etc.) or by food preference Vegan, etc. Possibly use the food court as a communal dining area that includes menus from all restaurants. Entice customers into your restaurant by offering in-restaurant-only menu items. Or maybe the food court is the waiting area for restaurants to offer their appetizers and drinks. Then at meal time, patrons physically move to the restaurant location.
