I came here with a family member for AYCE dinner. Sushi Kui charges $23.99 for adults which I found to be a bit high (relative to some downtown joints which charge $20.95 or less). The maki was excellent (the spicy rolls were delicious - the rest were still a cut above average in my opinion), but what really stood out to me was the service. The manager was very kind - he paid close attention to our table and even asked if I needed a phone to call a parent to pick me up (I'm in university but I suppose I look younger than I am!). Again, it was a bit pricey but I thought the care that the restaurant pays to both presenting its dishes well and making patrons feel welcome was wonderful. It's an elegant restaurant that is worth a visit if you're in the area - if not, I'd recommend you take advantage of the 15% cash discount on take-out orders!
