A great, small little gem in the clamour of Artarmon, and funnily enough, situated right beside the station (yet you don't hear a thing!). The service is quick and efficient, the service is friendly and knowledgeable.
Went recently and a change which I love is instead of serving their green tea in glazed terracotta cylindrical mugs like most Japanese restaurants (with no handles - it gets too hot to pick up!), they now have mugs with handles! It really helps you to appreciate their delicious green tea while hot.
Me and my family are regulars here, and two dishes we always get are the soft shell crab spider roll (I love the addition of the sweet chilli sauce!) and the Salmon Lover's Roll, with generous slices of sashimi and avocado. The teriyaki chicken is sweet and accompanied with sesame seeds, and the mashed potato salad that comes with many of the sushi dishes is a lovely surprise. Their rice is spot-on.
Value is all right. It's not particularly cheap, but won't empty the wallet either. Lunch was $55 between the three of us, and we still had about five massive pieces of sushi to take home with us, which they helpfully put in a takeaway box for us (which I think was complementary).
Definitely a must try :)
