Finally made a visit to Sake Bar Kushi after work as it's just a few blocks west from Yonge/Eglinton.
It's very roomy inside with booths along the sides of the restaurant, main bar and another bar(?) seating area in the middle, where we were seated. The servers were very friendly and helpful in choosing what to eat & drink. They were attentive with filling our drinks and bringing out our food in a timely manner.
Loved the tonkotsu ramen the best but all ten dishes we shared were delicious. We left full & happy. This restaurant is pretty understated as it's not on a main road but I highly recommend this place!
