content: I've never had a bad time at Koi, I don't know why it seems so many other reviewers hated it. Yes they do add a 18% gratuity but I appreciate that cause I don't have to tabulate a tip. I love their sushi, specifically The Minnesota I think it's called. It comes out really hot with yummy spicy mayo and it is to DIE for. There's a older asian lady who works there who is a hoot! She has a great sense of humor, you really must talk to her.
