Island famous for its bars? (8)
I believe the answer is:
alcatraz
'bars?' is the definition.
Both the definition and answer are singular nouns.
Perhaps you can see a link between them that I can't see?
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for alcatraz that I've seen before include "Federal prison in California, 1934-63" , "Pen" , "US island, formerly a famous prison" , "Old Calif. offshore prison" , "Once-notorious prison in San Francisco Bay" .)
