Check girl underground gets drinking bowl (7)
I believe the answer is:
chalice
'drinking bowl' is the definition.
(large drinking vessel)
'check girl underground' is the wordplay.
'check' becomes 'ch' (I've seen this in other clues).
'girl underground' becomes 'alice' (as in Alice in Wonderland).
'ch'+'alice'='CHALICE'
'gets' acts as a link.
(Other definitions for chalice that I've seen before include "cup used in company with host" , "Church vessel" , "Large goblet for consecrated wine" , "Church wine cup" , "Wine cup used at Christian Eucharist" .)
