I totally agree with Rob M. and Jon K.
This is the real thing. My wife and I have eaten at many sushi restaurant's in Calgary and abroad and this is consistently our favorite. We have never had a bad meal or anything but great service at Sushi Hiro. the sashimi and sushi is always top notch and very fresh. This isn't the place for silly fake Californiaized sushi. It's as authentic and as fresh as it can be in landlocked Calgary.
Give it a chance and as has been mentioned be adventurous and ask the chef for today's best choice. You won't be disappointed.
