Soda with lime or rum for convenience (6,4)

I believe the answer is:

ladies room

'for convenience' is the definition.
(ladies' room is a kind of convenience)

'soda with lime or rum' is the wordplay.
'with' says to put letters next to each other.
'rum' indicates anagramming the letters (rum can mean strange or unusual).
'soda'+'lime'+'or'='sodalimeor'
'sodalimeor' is an anagram of 'LADIES' ROOM'.

I've seen this clue in The Times.
