I believe the answer is:

oasis

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

'place of refreshment?' is the definition.
(I've seen this before)

I can't explain the rest of the clue.

(Other definitions for oasis that I've seen before include "Noel & Liam's band" , "can provide welcome relief" , "quiet spot" , "Desert refuge" , "haven for travellers" .)

I've seen this clue in The Guardian and The Globe and Mail.
