Roberta's, Brooklyn, NY.
Sure, Bushwick is luring plenty of 20-somethings in, but it's a rare thing to see a former president and past (and possibly future) presidential candidate and secretary of state make the trip deep into Brooklyn for anything. But leave it to the power of Roberta's to do the trick. The pizza is so good that Bill and Hillary had to stop by the place the New York Times described as looking like a "cinder-block garage space," but also "one of the more extraordinary restaurants in the United States."
If you haven't experienced the place before, it is indeed worth the hype. Ingredients grown on site, if they aren't lovingly sourced by the chefs who might not look like they take anything seriously, let alone making you something like a pizza, help make basically any pizza on the menu one of the best you can find in America. From the "Famous Original" to "The Speckenwolf" which, yes, has speck and mozzarella on top, the Clintons had the right idea making the trip.
