Came to Kaka when it was still in their earlier days. Back when we came we had to make a reservation a week before because they get packed quite quickly. My understanding is there are set times to dinners, especially on weekends. Upon sitting down you get an ipad to pick your order. Every table will get a special plate of daily fish that you cannot order again. (not sure if that has changed since we went back when they first opened). Kaka is quite known for their pressed and torched sushi. At first they were good, but after ordering a second time you get tired of the selection. The rest of the variety on their menu is average. Some of the skewers were good but nothing too special you can't get elsewhere. Their dessert selection is a little bigger but when we went a lot of stuff were either unavailable or sold out for the night.
A typical AYCE sushi restaurant would be a 3 star because you don't get the best quality. This one i'm giving a two because it is a bit more pricier than your standard AYCE. Service was good though when we went and food came out quickly.. but if you were to ask if I would go back again, I would say no.
