Kitchen United announced its next batch of cloud kitchens in an aggressive push for 15 open locations by the end of 2019.

The California-based company has signed leases in San Francisco and Los Angeles, plus a second location in Chicago’s Fulton Market District. The company currently has operating facilities in Pasadena, California, and Chicago’s River North neighborhood. It had previously announced locations in Atlanta; Columbus, Ohio; Austin, Texas; and Scottsdale, Arizona.

Each of the locations are near young, digital consumers, and the San Francisco space brings more restaurants to the concept with retail and outdoor seating in a business area with few food options.

The locations are currently looking for restaurant partners.
