I missed this at the end of last year, perhaps because I live in a small town in the north of England rather than a bustling metropolis:
Welcome to the world of ‘dark kitchens’ – fully-equipped commercial kitchens like you’d find attached to a restaurant, except with no restaurant or even a takeaway counter. Also known as virtual kitchens, they are dedicated solely to meeting the ever-growing hunger for online delivery services, facilitated by the likes of third party delivery apps.
These kitchens are anything but dark at peak times such as Friday or Saturday night, as noodles, pizza, curries and much more exotic—and increasingly, healthy—fare is sizzled up on a made-to-order basis while drivers for food delivery platforms such as Just Eat, Deliveroo, Seamless, and Uber Eats wait outside.
Incredible and obvious at the same time.
