I've been searching for years for my next AYCE sushi spot, and unfortunately this is not it. :(
20.99 for AYCE is actually not bad at all and very cheap, but I was expecting a little more in terms of quality. They had all the AYCE basics including dynamite, spider, green dragon, etc. and I was even surprised they had takoyaki and chicken katsu! This was a really great find because even some of the best and expensive restaurants in Markham don't offer them. Why I rate them only 3 is because the portions for some of the anticipated dishes such as teriyaki chicken and steak were soooo small. Like little slivers. I also left full, but not satisfied. Ever had that feeling? Service was very good and attentive. Wait times were minimal.
I give gallery sushi 3-3.5/5. The unique finds and service were really great, but I was not completely satisfied. I would come back again though, perhaps to try their bento boxes.
