I believe the answer is:
ritz
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">luxury hotel</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for ritz that I've seen before include "Ostentatious luxury" , "Cesar --, Swiss hotelier" , "top hotel" , "Elegant hotel" , "Posh hotel" .)
