I've been to Li Ao in Nolan Hill a few times now, usually for the happy hour. We've had their regular menu a couple times too.
I found the rice to be hit or miss. It would be perfect and soft one visit, and hard the next. However, they're generous with their fish portions and the quality is great.
The service is inconsistent depending who you get. I don't know her name, but the main server who's usually there was always attentive. She was absent on our last visit and we noted the difference in service from the one who served us. They also tend to forget to include soy sauce and wasabi with any leftovers.
The food always comes out quick and hubby and I are almost always in and out within 45 minutes. They've adopted Kinjo's pocky treat model sans goofy acts thank God.
Li Ao is simple, and the only decent sushi choice within the deep NW. To be fair, both their SW and NW locations are in the middle of bumf*** nowhere extremities of Calgary but they're convenient for suburbanites. It's a 10 minute drive for me, so I will keep returning to satisfy my late night sushi cravings but I'd go to Zipang for a more substantial meal.
