Located in Simi Valley, and serving Moorpark residents, welcome to Hai Sushi. Japanese Food. They offer Teriyaki platters and Fresh Sushi. Also you can dine on Sashimi, an assortment of rolls, California Rolls, Tuna Rolls, and more. First of all once you try the sushi here you will be in love. Bring your friends. We eat here on a regular basis. The owners are so nice they treat you like family. They are open later than most sushi places in this city. Fish is always fresh and saki always warm.
