If you have a yearning for authentic oxtail soup or even Spam musubi, no need to head to Hawaii. A visit to downtown Las Vegas will do. The aloha welcome mat remains out at the California Hotel Casino, just like it has been for decades, except for the recently completed remodel intended to make the property more inviting. Even if you’re not staying there, a bounty of Hawaiian dishes await, dishes that are often hard to find on the mainland. The hotel’s general manager, David Lebby, told me that about 85% of his guests are Hawaiians, including transplants now living in California. Given the prevalence of islanders, the hotel truly must walk the walk when it comes to food. “In all of our restaurants, we serve familiar items to the folks from Hawaii, starting with wonton min to saimin to oxtail to butterfish to teriyaki chicken bowls and laulau,” Lebby said. The offerings vary by the hotel restaurants. At the aptly-named Aloha Specialties, the menu board features items such as the Local Plate ($10.99) of teriyaki beef, chicken and Spam musubi and an Aloha Bento ($12.25) that includes teriyaki steak, mahi-mahi, Korean chicken and a hot dog from Redondo’s, an Oahu company.

For the uninitiated, here are explanations for two traditional Hawaiian dishes: Laulau is a dish in which meat and fish are wrapped in either taro or ti leaves before cooking. Spam musubi features the canned, processed meat and rice wrapped in nori, a thin sheet of seaweed. Boyd Gaming Authentic oxtail soup is a bestseller at the California Hotel Casino in Las Vegas.
