First time going to KaKa. I had gone with 6 other people on a weekday for dinner. It was very full for 6pm on a weekday.
The ordering system is straight forward and fast. You write down the number the item is listed as on the menu and the quantity you want to order. Service was fast, they take the order in and food comes out within few minutes. They attended to us right when we asked for something.
The sushi was pretty good for all you can eat. The pressed aburi sushi was my favourite. As for the cooked foods - the flavour was only okay. The chicken wings had good flavour but they were very small. The chicken karaage was so small! It was more like popcorn chicken. Definitely not like your typical izakya chicken karaage . The sashimi tasted pretty fresh for all your can eat, except the butter fish tasted like it was frozen and unthawed as it tasted very wet. The shrimp and veggie tempura was fresh and huge portions. They listed 4 different veggies but only gave us 2 (yam and eggplant). Not sure if they actually had the other ones. But the batter was light and flavourful and the you could tell the oil was fresh.
There were tons of options and items that I did not get to try. But also there were quite a few items on the menu that was not available to order.
The desserts they had were good and had so many different choices. I tried the green tea creme brûlée, pana cotta, kaka ice cream and the truffle. The first three were unique and tasted good and not overly sweet. The textures of the brûlée and panacotta were pretty accurate in my opinion. The truffle on the other hand was nothing special it was one piece of chocolate and tasted just like store bought ones.
Overall you get a good variety of items. The special sushi rolls and aburis were unique and very tasty. The other items are pretty standard and what you'd kind of expect at all you can eat. I would say it is worth it if you're wanting to eat more sushi rather sashimi.
