Good stuff. I stumbled across their location in Perris and tried it out and I really really like it.
Their Kalua Pork is fantastic, and their Hawaiian BBQ beef & chicken is very, very good as well. I have it on good authority that their fried shrimp is quite good, too.
They have locations in Northern California, a ton in the greater L.A. area (Los Angeles, Orange, & Riverside counties), as well as a few in Arizona. They haven't come into San Diego yet, which is odd given the large Asian & Pacific Islander population there (as well as a bunch of people who like all kinds of different types of food). Maybe they'll head down there soon, who knows?
But if you like that kind of thing I do recommend them. Good stuff, indeed.
