4 stars simply because happy hour here is a STEAL. You get HEAPING amounts of food for so little $'s: regular-sized rolls for $5, fancier rolls for $7.75 and a smattering of other entrees like full sets of sliders, skewers for the same price. We ordered way too much food and left absolutely stuffed.
In terms of quality, I don't think this is the best sushi I've ever had, but the food was definitely not bad. It's good for a very filling meal, if not for the finest cuisine. I probably wouldn't eat here again for a formal dinner but the ambiance is kind of like a fancy sports bar / restaurant so it seems great for games. Service was also excellent: our waitress was the best!
