"Nearly 1,000 of [Uber Eats'] restaurant partners are actually 'virtual restaurants,' operating out of real restaurants but peddling entirely separate, delivery-only menus"

Eater:

Uber’s version of virtual restaurants are different; instead of relying on commissary kitchens, they take advantage of restaurants that already exist. As Uber Eats head Jason Droege recently told Eater, “They’re restaurant brands located in physical restaurants. And the brand only exists on Uber Eats.” In Dallas, for example, a small sushi chain called SushiYaa operates five brick-and-mortar restaurants — but those restaurants are also home to around two dozen virtual restaurants with names like Bento Box, Poke Station, and Mandu Dumpling House, serving entirely separate menus and dishes that are only available for delivery via Uber Eats.

“Because this concept worked so well for us, we actually changed one of our restaurants from a sushi buffet concept to a regular restaurant with 8 different virtual restaurant brands inside it.
