<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">pizzeria fixture</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for oven that I've seen before include "Cooking device" , "Compartment for baking" , "You can cook in this" , "Stove" , "It''s used for baking or roasting" .)
