We don't go to Koi often. But we know the sushi is safe and usually good. My only complaint is that they automatically add gratuity to everyone's tab. I don't know how they can legally do that. The service is ok. Sometimes you get a decent personable sushi chef, sometimes you don't. Sometimes you get a friendly server, sometimes you don't. We love their sushi tho... Spicy tuna, spicy philly roll, spider roll and some of the State named rolls.
