Touch screens! They're the first in Australia to have them, it's as close to being in Tokyo as you're going to get in Sydney and it's very fun. Each screen displays a different category: drinks, grills, sushi, etc. The food's good, there's plenty to choose from and they're open until 2am seven nights a week.
Don't miss the SUSHIan roulette - six pieces of salmon sushi are arranged like the barrel of a gun and one of them is jam-packed with wasabi. From the outside, each of the pieces is lightly painted in the massively hot paste so there's no way of telling which is the eye-waterer. Bam!
There's also a list of birthday cocktails where each non-alcoholic drink is designed around a birth colour - if you can prove it's your birthday that day they'll give you one for free. There's also a bottle-keep system - you can purchase straight spirits and if you don't drink it all, they'll keep the bottle until your next visit. Schweet!
