Maybe we were just lucky with our experience. My friends took me here for my birthday, it was a group of 6 and we were sat near the back of the restaurant.
The ordering was fairly straightforward, all the food came pretty quick and the service was nice. There were a couple items that were sold out but we weren't too bothered by it.
Because it was a fairly large group, we got to try everything on the menu, and for AYCE sushi, it's all pretty good. The only improvement I could see is changing the portion sizing for some of the dishes. For instance, when we ordered 1 dish of beef ribs, we got 2 tiny pieces lol which was ridiculous. But once we understood how that worked, we ordered 6 dishes the next round and got a regular portion.
I probably wouldn't go back unless it was for a special event because it's kinda pricey. But I didn't have such a negative experience as previous Yelpers and I went on a Saturday evening. Perhaps we were lucky or the restaurant finally worked out their glitches.
