This sushi on steroids place is KILLING it in St. George. Roberta runs the joint and she is awesome.
Fresh Ahi, Salmon and Octopus poke...daily. Excellent sauces, spices, etc.
If you haven't been to this place in St. George, go. You can also pick a pie up at arguably the best pie shop in Utah, Crowshaw's (get a Sour Cream Lemon).
It is located on Bluff Street behind the Pizza Hut and next to Tom's Deli.
