Premium brasserie offering shade (5)

I believe the answer is:

umbra

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

'shade' is the definition.
(I know that umbra is a type of shadow)

'premium brasserie' is the wordplay.
'UMBRA' is hidden within the letters.
But, I am uncertain how this is indicated.

'offering' acts as a link.

Can you help me to learn more?

(Other definitions for umbra that I've seen before include "Rumba (anag.)" , "Burma (anag.)" , "Dark shadow cast by earth in eclipse" , "shady region" , "Shade, or ghost" .)

I've seen this clue in the Sydney Morning Herald.
