'skeleton service?' is the definition.

'skeleton service?' is the wordplay.
'skeleton' becomes 'bone' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'service?' becomes 'china' (I've seen this before).
'bone'+'china'='BONE CHINA'

Can you help me to learn more?

(Other definitions for bone china that I've seen before include "eating off this?" , "fragile" , "Coalport" , "Form of white porcelain" , "Type of fine porcelain" .)
