I have said it before - sushi is easy as long as the fish is fresh.
Here's a perfect example of a place that has too much self worth and not enough customers.
The AYCE special was fair priced, average for sushi places, but the majority of the fish was on the edge of freshness.
The only thing that appeared to be fresh that day, was the Uni (Sea Urchin) and it was admittedly good. The portion was plentiful too.
The service was fine, but I was the only customer, so I would expect nothing less.
But in the end, even just one piece of week-old fish can really ruin the whole sushi experience - and a half dozen can turn you into a vegetarian.
