Hello, I am looking into using PrestaShop for a mobile project that I am working on for the food/restaurant industry. I will have customized sites for individual restaurants and plan to store the menus as products in the database and have checkout and payment processing. Are there speed or performance issues using PrestaShop in a mobile application? Is there potential scalability issues? Are there examples that would help to determine if PrestaShop is the right solution for me? Thanks, FoodFighter
