Recently our Grill'd Delivery service radius was reduced to 6km, this change was made so that we can ensure a consistent standard of product quality, have more control over delivery times, and reduce incidence of multiple drop deliveries.
That said, if you are within that range but still can’t see your local, it may be because there’s a shortage of delivery drivers in the area. This would be the same for third party providers.
Fingers crossed you’re able to get your burgers again soon!
