TGI Friday's is innovating in the casual dining space with a new app for iOS and Android that will allow customers to browse the menu, track their tab, and pay their bill. Customers can open a tab in the app by giving their server a five-digit code that syncs with the store's sales system, after which they can watch their tab update when placing orders. The mobile payment system is supported by Tabbedout, which has its own app allowing diners to pay by phone at a variety of restaurants. The Friday's app can currently be used at most than half of the chain's 600 restaurants, and you can grab it now from the App Store and Google Play. Just be sure not to let it interfere with your romantic ambitions.
