I just ate at the main King’s Hwaiian Restaurant in Torrance (there’s the full restaurant and then a smaller ‘stand’ type place located nearby). I don’t think it’s near the factory anymore. It was REALLY good. Although it’s kind of unsetlling they they use the same off the shelf Hawaiian bread at the restaurant. Literally it’s the packages of the bread rolls you buy at the store. They keep them in a warming drawer, tear open the package and put them on a plate. I ate at the counter and in the span of five minutes they went through 10 packages. It was incredibly wasteful.
Only place I have ever had macadamian nut cream pie and it was effing amazing.
