My first visit to Kaka was pleasant overall. For a Japanese theme AYCE, it's cooked food (grills) selection is weirdly better than its sushi bar's offerings. Not sure if we were there on a bad day but their sake (salmon) sashimi was 'bland'. Not stale yet not the freshness.
In general, Kaka employs the philosophy of using superior cooking skills to complement their more 'cost effective ingredients' used. Service was prompt and smaller portion size was ideal for AYCE.
At $28.99++, I might return.
