coffee bar

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

'cafe' is the definition.
(synonyms)

'anglican clutching iron rail' is the wordplay.
'anglican' becomes 'cofe' (I am not sure about this - if you are sure you should believe this answer much more).
'clutching' means one lot of letters goes inside another.
'iron' becomes 'Fe' (Fe is the chemical symbol for iron).
'rail' becomes 'bar' (metal rail or bar).
'cofe' going around 'fe' is 'coffee'.
'coffee'+'bar'='COFFEE BAR'

'in' is the link.

Can you help me to learn more?

(Another definition for coffee bar that I've seen is " Buffet".)

I've seen this clue in The Times and The Sunday Times.
