Grabb is astroturfing the crap out of reddit right now. Enjoy the freebies, but when it comes time to pay, you're way better off using the vastly superior app Ritual, which has more restaurants and WAY better UI/UX.
>Great for those situations I'm just going nearby quickly without bringing my wallet, e.g. going to the food court downstairs from my office to grab a quick snack or coffee.
In Toronto we have Ritual. You order/pay on your phone and your phone notifies you when to leave for your order to be ready.
A lot of stores got onto it and it is by far the best way to order lunch.
... and once you've used up you Grabb credit, you can download the competing (and vastly superior) app, Ritual.
