This sushi place is clean and casual and the workers and owners are nice people. Hiroba is the only sushi place in town that uses black rice. I've never heard of black rice until I tried it at Hiroba Sushi and it's sweet and tasty! They offer noodle and rice plates for those people in your group that don't like sushi. It's a great compromise between me and my boyfriend. Menu prices are reasonable without sacrificing quality. Sashimi is always tastes fresh and they usually have unique fish specials, like toro (which you would probably only find in a fancy restaurant on Las Vegas Blvd). The 4-star rating is based mainly on the quality of the food and cleanliness of the restaurant. Waiter service is mediocre, but the sushi chefs are excellent if you sit at the bar. Again, this is a casual restaurant so don't expect it be some 5-star restaurant. This is my favorite sushi place in town and will definitely be back soon!
