Duncan's On The Gulf at 490 Dock Street, Cedar Key, Florida.

Terrible. Poor service, expensive fried grouper fingers were only warm. Some were well cooked, others lightly. When I complained about not being hot, they apparently dropped the same grouper back in the fryer to heat them up. NOT fresh, had that grainy texture of long-frozen fish. Also the grouper should have been flaky, but had a rubbery snap to it.
When getting our check, heard the staff complaining they could not do checks or cook food because the computer was down. ???
Another waitress was heard mumbling under her breath, "it's always something about this place. Always something."
Avoid this place - GREAT other choices here on Cedar Key.
