Coming from the Toronto/Markham area, I have very high expectations for AYCE Japanese restaurants in terms of quality, creativity of dishes, service, environment, etc. A friend recommended Sushi Crescent to me and I've got to say, I'm very, very impressed with all aspects of our lunch AYCE meal.
We arrived at around 12:30pm on a Saturday and were pleasantly surprised that the place was already about a third to half full. Service was very quick and all the waitstaff were extremely polite, friendly, and always noticing empty water glasses, empty teapots, empty dishes, etc. The tea was a roasted rice tea, which was definitely a very nice change from the usual bland green tea at AYCE places. The menu itself wasn't that creative and didn't have too many options, but there was a fair selection of sushi, rolls, appetizers, small fried dishes, ramen/udon/fried rice. The only dessert they have are green tea, red bean and green tea ice cream, which is a bit disappointing. What I found great was that after you placed your order, you received a small checkbox sheet with what you had ordered. That way, you could be sure you received all the things you ordered and it definitely prevents you from over-ordering and wasting food afterwards.
Expectably, there was no sashimi on their lunch menu, it was $16.99 per person plus tax and tip which I'd say is a very reasonable price for the high quality and stellar service. There are 2-3 small outdoor patio tables (you'd have to bring your order inside to get it taken down), a large upstairs and front and small back room on the main floor. There's only 1 stall for the male and female washroom, so not the most convenient.
