Tanaka's is one of the best sushi spots in Charlotte (and I'm somewhat of a connoisseur)! All of the rolls that I've tried have been amazing, not to mention the fantastic sushi chefs that will make any roll of your choosing modified to your unique specifications.
The freshness and originality of the rolls is superbly matched by the personality and friendliness of the "sumo chefs". I used to live very close and would frequent often to take advantage of both its friendly staff & its many specials. Give this place a try, you will not be disappointed!
