Just a quick update. Giordano's has responded promptly regarding my experience & has apologized for the cold pizza. Hopefully getting pizzas out to tables more promptly will rectify the problem as running it outside is not where the problem lies. When you already wait for quite awhile for your pizza to cook I kinda didn't want to wait anymore for it to be re-heated.
Also plans are in the works to get the water filtered for the downstairs dining area. So for future diners, things looks very promising for you to have a good dining experience. Management takes negative feedback seriously. I commend them for that.
My next update review will have to be when I return to Vegas. Maybe another three years?
