Cracker brand (4)
I believe the answer is:
ritz
'cracker brand' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for ritz that I've seen before include "Luxury hotel" , "Posh hotel" , "Elegant hotel" , "Swiss hotelier, creator of a chain of elegant hotels, d. 1918" , "Piccadilly hotel" .)
