Grabb is a Toronto-based mobile app that aims to help people skip-the-line at busy downtown restaurants. The app, which is available for iOS & Android, lets users pre-order and pre-pay for meals at over 30 restaurants in the King West, Queen West and Financial core including Hero Burger, Aroma Espresso Bar, What A Bagel, and Buna's Kitchen.Other mobile food apps like Tab and delivery app Just-Eat are already popular with Torontonians, and with Uber Eats rumoured to launch its delivery service here soon, there couldn't be a better time to be launching an app for hungry downtowners.
