There might be Japanese staff at this place, but the rice is not authentically prepared sushi rice, and thus is as close to real sushi as an AYCE place, and at least at AYCE the price matches the low quality.
Fune and it's old, run down dining room aren't worth the prices here.
For authentic Japanese food, owned and operated by someone who is Japanese, in a beautiful modern open decor try Yutaka on Dundas, it's the real deal and the food is as artistically presented as it is delicious.
Watch the documentary Jiro Dreams of Sushi and learn what the art form is really about. Fune isn't it.
