Midori is a great place for sushi in Calgary. It's hard to find somewhere with decent sushi without paying an arm and a leg but Midori is one of the best I've found so far. I really like the "crunch" rolls (although the tempura bits cannot be good for you). The Caterpillar roll is my favourite so far, I think.
My only complaint is that they never refill water... so service is a little lacking. I drink a lot of water; when I drain the glass within the first 10 mins, a refill might be nice. Soy sauce is salty! And when everyone at the table is in need of water, definitely an indicator!
All in all, I'll be back, though. A place definitely worth a visit (or 2)
