I've been to Wow a few times now and have found them to be pretty consistent. The place is really small but is never too busy (which concerns me!). Their lunch menu is pretty good value at $10-$13 which includes a salad and miso soup.
My go to lunch menu item is their Katsu Don which you can have with either fried pork or chicken. The portion is generous and the taste is great. The one thing to note is the meat you choose is always in the rice already and the breaded meat is no longer crispy.
For rolls, my favourite is the Narudo roll which is wrapped in a cucumber instead of rice.
I've taken out their platters before too and can say they are pretty good value and have a decent variety.
For me, the location is a 2 minute drive from home and is an easy choice if I'm craving for some quick sushi. Recommended.
