After having been here many times, I feel like the quality went down a little. The last visit just confirmed it for me. I'm a sucker for salmon nigiri and I love the buttery smoothness of it. Although the salmon nigiri here is rationed appropriately (there could be a bit more fish), there was an off taste to it, as if it had been sitting out too long. I didn't get sick from it, but I know my fresh salmon.
The one thing I do enjoy from here is their baked rolls. Make sure you try one of them. Other than that, you could get a better experience at another AYCE that offers more appetizers and fresher fish.
