This small restaurant found in a humble strip shopping center on Roswell Road is simply amazing! The fish is flown in daily from Tokyo's famous Fish Market. They have a small sushi bar and otherwise table service. In addition to sushi (long list), they have tempura, teriyaki, and other cooked foods - so it suits all palates. Everything that I've had and tasted at Circle Sushi is delicious. And the service is great.
Additionally, for fun, they have a tv on the wall showing Japanese television shows. Circle Sushi serves sake, wine and Japanese (perhaps others) beer. Very authentic and enjoyable.
