Amazing Hawaiian food by Henderson. There are 3 parts to this restaurant. The Hawaiian Express, Poke Express and Sushi bar/restaurant. I've never eatten at the Sushi restaurant, only at the Hawaiian food and Poke Express.
The Poke is really awesome. If you like Tagu, it is sweet and chewy and very authentic. The shou Poke and spicy poke is great also. If you are a poke fan, do try Poke Express.
I usually get the Bento Box A with Garlic Chicken. It is a huge meal with rice, Teri beef, garlic chicken, spam and noodles. Very flavorful and filling. My wife gets the tuna bowl. That is huge also. Great flavors with the tuna and rice.
They have Oxtail soup on Saturdays all day and after 600pm other days. I like this and it's very authentic. You combine the rice and ginger and green onions and you have a cornucopia of flavors and textures in that oxtail soup. It has been the best I could find so far in Las Vegas.
I would pass on the Saiman. The noodles are good, but the broth is not as flavorful as the other places I've tried in LV.
Overall, the go-to spot for Hawaiian food this side of town.
