I'm no expert but I enjoy sushi and have had plenty on trips to Japan.
For what it is, I thought this was fine. Service was fast, probably too fast. A starter should be at least partially consumed before you start bringing mains but if pacing is the worst thing you can say about someplace if say they're down well.
We snuck in right before happy hour ended so we benefitted from some discounted food. The chimichanga sushi was excellent and all others we ordered were at least good.
