Umami Restaurant Group has plans to grow the fast-casual U Mini variant, along with full-service sister brand Umami Burger.
The U Mini name may not stick, so the design features the Umami Burger logo throughout.
U Mini in the Westwood Village neighborhood of Los Angeles is about 1,200 square feet.
A digital screen lets customers know how their order is progressing.
The test unit has indoor and outdoor seating, but most orders are expected to be to-go.
