SAN FRANCISCO — The bar at the Elite Cafe here was packed, but not a drink was being poured. The champagne stand sat empty and warm. The tap was covered in plastic wrap.

Instead, the restaurant was flooded with the low din of typing. That’s because the Elite Cafe, from 8:30 a.m. to 5 p.m. every weekday, is not exactly a restaurant anymore and certainly not a bar. It is a co-working space.

Everything is now a co-working space, one of those shared offices that are popular among freelancers, small companies and other workers who want a change of scenery. Coffee shops are co-working spaces. Gyms are co-working spaces. Social clubs are co-working spaces. And now restaurants — but only before dinnertime.

The company that laid the extension cords and power strips across Elite Cafe’s copper tables is called Spacious. Since it was started two years ago, Spacious has converted 25 upscale restaurants in New York and San Francisco into weekday work spaces. Membership, which allows entry into any location, is $99 a month for a year, or $129 by the month. With $9 million in venture capital it received in May, Spacious plans to expand this year to up to 100 spaces.
