The Internet-driven sharing economy opens all kinds of new opportunities for exchange. Restaurants provide precious public space in city centers and now a new app, Spacious, is turning upscale restaurants in New York into office spaces during the day. Members, after a free trial day, can subscribe to Spacious locations for $96 per month, or $29 for a day pass. Participating restaurants are reporting that users often stay on to eat once the restaurant opens for the evening’s dinner service.
