Kaka used to be a 4.5-5 star AYCE sushi restaurant, but the quality and value for money has declined noticeably in the last year.
The menu used to include stuff you wouldn't the find at other AYCE places, like brussels sprouts and a tasty fish taco. The last two times we visited, those items were gone, and the menu was back to a typical AYCE one. Maybe we had a different chef/cook the last 2 times, but the food we did order also seemed lower in quality; maybe they changed their supplier too?
With this change in quality, there wasn't a change in price, which really bugs me. Kaka charges a pretty premium price for not so premium food.
