I don't really think anyone comes to Poland expecting to get fantastic sushi. Given that, I would…read moresay the sushi was good. Compared to what I get at my normal sushi places, it was maybe ok. My biggest concern/suspicion is whether the fish was fresh. We did come in on a Sunday, so perhaps there was a reason they were slow, but if they don't have more clientele than this, I can't imagine they would be able to support fresh food.
The service was good, not great. We were one of 2 tables during the entire course of our meal, so they weren't busy. Our beer wasn't brought until after our food order was placed. We had to ask a couple different times for refills.
Its not a place I would go out of my way to eat at again.
