Calgary needed a sushi place like this, reasonably priced, great atmosphere and quality. The decor is above average, you can tell that they put a lot of attention to every detail and perhaps that's the reason why the grand opening of this restaurant was delayed by so many months.
As for their menu, their oshi sushi are delicious (especially the spicy salmon and philly), and so are some other items like the deep fried mochi balls, grilled vegetables and beef cuts. They also have a decent selection of sakes to choose from. Nothing I've ever tried at Ke has left me disappointed, or underwhelmed.
Service is very friendly, and for quite an experience, make sure to sit by the bar for a view of the always-busy kitchen.
Also noteworthy, they have adopted the Kinjo-esque practice of giving away Pocky sticks to women and children every visit! Ke is definitely a welcome addition to the neighbourhood.
