I've eaten here twice, well, once. The first time was when this location was "Hello Tokyo" I loved the sushi they had, was delicious, comparable to my usual go to place.
The second time I ate here, was when it turned into Sushi Hero. The sushi wasn't bad, but it just wasn't the same. The price is pretty high compared to other all you can eat sushi places. To make up for that, they carry a stamp card, so we can at least get a free meal every once in a while. The other upside, or maybe downside depending on who you are, they place was completely empty during lunch time. Makes me worry about how long the business will last.
