I've tried Aikawa twice now, both times for lunch, once as a group of 6 at the restaurant itself and once for take out also for a group of 6 coworkers.
I really enjoyed it! Not the best (aka Maiko sushi) but really decent option if you're in DDO.
We got great service both times, in the restaurant and the waiter who delivered the food to us.
I never actually paid but it doesn't seem too expensive. Wouldn't mind having their sushi again!
