For a big city, there are really not a lot of sushi places in downtown Calgary (but there are lots of Tim Hortons locations - don't get me started!)
Since the unfortunate fire at Sushi Hiro (and again, who expects a fire in a place that serves raw fish?), I have been looking for a place to sate my appetite for tekka and wasabi... and this is the place I have settled on. Previously located in an island-like kiosk in the centre of the Scotia Centre food court floor, they have since relocated to a hip and very mod kiosk on the side. While it is still not restaurant-level sushi, it is probably the best food-court sushi I've had in Calgary. Their spicy salmon and tuna rolls are pretty good, and they have a good selection for sushi newbies too (if your definition of sushi does not extend beyond California rolls). Is run by a truly charming woman with a wonderful smile and excellent marketing skills, her sincere charm will keep you coming back (plus she's cute!)
In my "dream Calgary", we will someday have at least one good "corner sushi bar" at least every two blocks in downtown Calgary. But until that happens, places like Bento Zushi will have to fill the gap. Recommended.
