The article of Bloomberg Technology explains the case of the startup Spacious, which has a network of five of these hybrids restaurant-office. This startup has found a niche among people looking for a place to work that is less expensive than a coworking space, but quieter and more reliable than a cafeteria. It is not the only business that has made this shift.
At Bloomberg they say that "the model of converting dining rooms or bars into shared offices is attractive to restaurant owners because it offers a new source of revenue during the work day, when their spaces are usually left dormant. It’s especially appealing to the food-service industry, which has seen its already-low margins squeezed".
They offer Wi-Fi, printers, office equipment faster and coffee. They have all the features of a coworking space, but are half price. The article also reflects the opinion of Daniel Rubin, who says it is not easy to find a restaurant or bar that can be "presentable" for professionals who work every morning.
