For me, my quality barometer of a sushi place is its uni (sea urchin). If the uni tastes clean, smooth, and creamy, then this place is worth coming back to. What's your barometer?
The surprising part of this quality place is that they have AYCE. Most AYCE places reserve only the cheaper slices or they load the orders up with rice. SK didn't have a crazy amount of rice with the sushi, so you're ok there. Sure, there are restrictions on the quantity on some of the good stuff, but that's to be understood. Just know that it's tasty and the fish is fresh.
I did have to take a star off because the service wasn't consistent, even in the same visit. Not a deal breaker, but still worth noting.
