The Washington Post has a trio of articles on pizza:

First up is The Best Pizza in America, Region by Region.

We set out to find the country’s best pizzas, from slice shops in New York City to fancy California-inspired pizzas, gathering favorites from experts, historians and pros around the country. For a more populist view, Washington Post data columnist Andrew Van Dam analyzed 7.5 million Yelp reviews of pizzerias to see which regional-style restaurants attract the most and highest ratings. But who has the best? Well, that’s for you to argue.

The article goes on to list the top five pizza shops in the US for five different styles (NY, Chicago, Detroit, New Haven, and Neapolitan(ish)):

Next up is an article slicing and dicing a ton of Yelp reviews to try and map the popularity of styles across the US:

At the other end of the scale, our maps emphatically paint the American South, especially the Deep South, as a pizza desert — though we’ll point out again that we’re ignoring Pizza Hut, Domino’s and other huge, national chains. It’s possible that Alabamians love pizza as much as Pennsylvanians — they just prefer it standardized, homogenized and delivered in 30 minutes or less.

There's a ton of gems in there, and the page provides plenty of maps detailing all kinds of pizza related things in the US. And it of course touches on the "pineapple controversy". (My stance on pineapple - if you like it, go for it. Who am I to judge? It's not like you're putting Swiss cheese or anchovies on a pizza).

And finally, the Washington Post has a map to find the best pizza in your state, by style.

I'm delighted to see that My Friend Derek’s shows up as the #1 Detroit style pizza for Washington State, and as second place overall. (Derek is a former Omni engineer and I'm super jealous of what he's got going on these days). His pizza is top-notch.

However I'm slightly annoyed that The Carlson Block didn't make a showing for Washington. This only goes to show that the method they've used for determining the best pizza can't be completely accurate. These lists are always meaningless when it comes to actual quality, but it does provide a great resource for places to check out.
