"If a sushi takeaway is frequented by Japanese expats, you know it's legit. Atariya is no nonsense sushi made with excellent ingredients. The queues are long, don't expect stellar service. They tend to be quite generous with wasabi, you might want to request them to go easy. Unless of course you enjoy the thrill of a momentary seizure caused by accidentally swallowing too much wasabi or are a Samurai."
