For those Chowhounds in OC craving Hawaiian food like myself and wanting more options than L&L Hawaiian BBQ and can't make the drive out to Bruddah's or Bob's Okazu-Ya in Gardena, I've run across another option in Tustin, called Maui Island BBQ.
Maui Island BBQ
13931 Carroll Way Suite A
Tustin, CA 92780
Hours: 11AM-3PM, 5:30PM-9:30PM Mon-Sat, open until 10PM on Fri & Sat
This may have been a former Japanese restaurant, as the interior decor looks like a traditional Japanese restaurant, and it does have a sushi bar. About the size of a hole-in-the-wall restaurant, with maybe 7 or 8 tables, but very clean and nice inside, darkly lit, with candles lighting each table.
Most of the dishes are lunch plate specials, with BBQ chicken, BBQ beef, short ribs, loco moco, grielled salmon, chicken & shrimp cutlets, etc.
The food isn't quite as authentic Hawaiian as Bruddah's or Bob's Okazu-Ya, but it is pretty good. I had their BBQ combo dish, which had BBQ beef, BBQ chicken, short ribs, and 4 California sushi rolls, along with a salad and some steamed rice. That combo was $9.99, among the priciest of the dishes on the menu, so not a bad deal for the price. I was definitely stuffed after eating all that.
Off the 17th St. exit in Tustin, right off the 55 freeway, there is a Mimi's Cafe next to the restaurant.
Highly recommended, and I will definitely go back.
