I'm officialy a fan of sushi one. This place is conveniently located right across my workplace, so I go here often.
Their lunch special is very reasonably priced for a sushi joint, I'd rather go here to have the lunch special rather then having to buy fast food at sheppard center.
Regarding the AYCE, I think this is one of the best that I've ever been in terms of quality and preparation (Tip: Go before or after lunch hour if you're going for AYCE since it tend to get overly crowded during lunch hour, and the food will take forever to come during that time span, making AYCE a bad option)
Overall, I'd definitely come back here whenever I'm having sushi craving.
