I've been to Sakura Garden twice for AYCE, and I've been happy with both times I've gone. The price for AYCE (Even on weekends at lunch for $14) is unbeatable. The sushi and sashimi are fresh, and tasty - much better than the ones I've tried in Mississauga or Oakville. Menu has your standard kitchen items, and there are plenty of rolls to choose from. Service is attentive, although slower when busy (I believe they have 3 waitresses and 2 line cooks).
Place is quite small, but cosy. Price is the biggest factor though since at $14 for lunch or $23 for dinner (I think), it's very competitive.
