Kimonos is WAY better than Pucks. We have had sushi every place it's offered in WDW, being sushi fans. This is how they rank, in our opinion.
Kimonos - #1 - Swolphin caters to a large Japanese market - this is the most authentic sushi on property
Cali. Grill - Very good, esp. the rolls which are HUGE
Pucks - Very good also, but a little behind CG
Tempura Kiku / Matsa No Ma Lounge - good, but they have to make it in such large quantities that they premake alot of the items & it gets a bit dried out. But, if we need sushi for lunch, this is about the only option so we do it occasionally. It is our last resort for WDW sushi.
