Shellfish place so fantastic (7)

I believe the answer is:

escalop

I'm a little stuck... Click here to teach me more about this clue!

'shellfish' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.

'place so fantastic' is the wordplay.
'fantastic' is an anagram indicator (a fantastic or improbable ordering of the letters).
'place'+'so'='placeso'
'placeso' anagrammed gives 'ESCALOP'.

Can you help me to learn more?

(Other definitions for escalop that I've seen before include "Bivalve" , "dish" .)

I've seen this clue in The Independent.
