saloon

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

This could be a double definition.

'in this you may drink' is the first definition.
The definition suggests a singular noun which matches the answer.

'drive' is the second definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe there's an association between them I don't understand?

'or' acts as a link.

Can you help me to learn more?

(Other definitions for saloon that I've seen before include "Bar room" , "US bar - type of car" , "Car; public room" , "Bar or shape of car" , "An American pub, as in the wild west" .)
