I went with a few friends, and we all thought it was very good. They ordered more traditionally, but I ordered off the blackboard special and it was outstanding! The New Volcano roll that another reviewer raved about it. It was absolutely delicious. I was blown away in a way that has not happened in much fancier sushi restaurants.
If you go when they are busy, it can be a bit slow as they seem to do a brisk take out and delivery business. But they recently obtained a wine/beer license so you can relax with a sake or a bubble tea and enjoy an appetizer while your sushi is prepared. Very friendly service. Small parking lot and plenty of free street parking. Very reasonable prices/serving sizes.
Okea is outstanding for a small local place. Highly recommend!
