Sounds a bit like Cravings by 99 Ranch in Chino. I like the concept and I'm not sure why it hasn't taken off more. I think the H-Mart implementation of it at Culver/Irvine Blvd is fine but could use more restaurants and more money into the actual execution of the spaces. There's also Mendo at Whole Foods Jamboree/District and the smaller options at Zion Market on Irvine Blvd for smaller-scale food court/grocery that is nicer than say, a Costco food court.
edit: Totally forgot about 99 Ranch and Wholesome Choice food courts in Irvine, though both are a little sad and could use love. Gelsons also has a limited bar/food situation that.
