Had a chance to go here to today with some family for lunch.
We ordered a few different sushi rolls for lunch - the Spicy Tuna Roll and a California Roll being our rolls of choice. I thought the sushi was good, but not great by any means. There wasn't anything in particular that separated it from other sushi I've had at other places in Charlotte like Soul and Pisces
I thought the service was great - attentive, quick, no issues there.
Prices are reasonable and are comparable with other sushi spots in and around the Charlotte area.
I wish I could give Tsunami more than 3-stars, but I think this place deserves an average rating for average sushi.
