O'Sushi is, as stated in other reviews, hit--or-miss. Sometimes, it's all right, but recently, the establishment seems be be lacking in quality in regard to service, taste and presentation.
On my most recent trip, I was charged for two ginger salads which I never received, and the rice around the vegetable rolls seemed excessive and chewy.
It certainly wouldn't be my first choice for sushi.
We always order for take out. They are ready in less than 20 minutes and the food is always good. The Sunday Morning Roll and Buffalo Roll are our two favorites. The fried tempura roll coming in a close third.
