There is a new All-You-Can eat sushi place at Appleby/Upper Middle . I think it's called Sushi Adano..could be Amado or something similar..Anyways-it's in the plaza next to Canadian Tire.
I haven't tried the AYCE (this never appeals to me), but we've had take out twice and I'm very impressed!
First of all it's probably the cheapest sushi place I've been to..prices are great!
More importantly, the food was very good. I seem to expect less from places that offer All-You-Can-Eat, but the rolls we ordered were very large with good fish and not overfilled with rice. The tempura was perfectly cooked, and again have to say the portions are bigger than any place I've had in Burlington with much lower prices. (Rolls around $6, tempura apps $7 huge seaweed salad $3)
The space is very nice too..they did a good job renovating from an old "AppleJacks"..only problem was slow service at the front of the house..they don't have someone at the front and don't seem to notice when people come in.
