Great staff. Great sushi... best in the area with the exception of K's Asian Bistro in Hampton. The wait is incredibly long. No call ahead or reservations. Take out orders are rarely ready in time.
Here's why two stars...the management/owner is incredibly rude and unprofessional. I have been to the Mermaid over a half dozen times and last night may have been my last. I was with a party of six and we knew that there always is a wait so we had a couple beers at the bar and placed our food order there. We kept it very simple by just ordering about three rolls of four different types. The order was ready and the owner would not serve us because there was no table for us, even though there was outdoor seating for about 30. After a not not so friendly discussion with the owner, we were permitted to eat outside. It's almost funny that we had to negotiate with the owner to spend ~$500 at her establishment.
Bottom line... very good sushi and wait staff. Very poor management and ownership.
