Drink from the bar, oddly (3)
I believe the answer is:
tea
'drink' is the definition.
(tea is a kind of drink)
'the bar oddly' is the wordplay.
'oddly' means one should take alternating letters.
'the'+'bar'='thebar'
The alternating letters of 'thebar' are 'TEA'.
'from' acts as a link.
(Other definitions for tea that I've seen before include "US party" , "Evening meal - eat up" , "Common drink" , "Popular beverage brewed at home" , "Oolong, for example" .)
