The old trope about pizza and sex is such well-worn territory at this point that I won't even bother repeating it, but I will say this: just because something is generally good, doesn't mean it can't be better.
When it comes to pizza, there's a simple request you can (and should!) make at most garden-variety pizza joints that far too few people realize is available to them: order your pizza well-done.
"Well-done?" you say incredulously. "That's how you order a steak if you hate flavor or if you're the president -- what does it have to do with pizza?"
To put it simply, asking for a standard delivery pizza well-done can often upgrade a run-of-the mill-pie, or an edge-above-average one towards transcendence. The crust gets a little more savory depth. The cheese has more of those delightful browned spots. Basically, the maillard reaction has had a little more time to do its thing, which means more flavor for you at zero extra cost, save for maybe a couple more minutes of waiting time while they cook it up.
I'm a Chicago-area native (calm down, deep dish isn't even a part of this discussion), and a well-done order does particularly wondrous things for your standard square-cut Chicago-style thin crust, browning up the cracker-y crust just a little bit extra and making sure the cheese is in possession of its fullest flavor. One time I forgot to make the well-done request from our family favorite (shout out to Ledo's) and my brother was NOT pleased. It still tasted good -- but it wasn't everything it could have been.
