#1 Frank Pepe’s, New Haven, Conn. (White Clam Pie)

If you want to discuss the loaded topic of America's best pizza with any authority, you have to make a pilgrimage to this legendary New Haven pizzeria. Frank Pepe opened his doors in Wooster Square in New Haven, Conn., in 1925, offering classic Napoletana-style pizza. After immigrating to the United States in 1909 at the age of 16 from Italy, Pepe took odd jobs before opening his restaurant (now called "The Spot" next door to the larger operation). Since its conception, Pepe’s has opened an additional seven locations.

What should you order at this checklist destination? Two words: clam pie ("No muzz!"). This is a Northeastern pizza genre unto its own, and Pepe's is the best of them all — freshly shucked, briny littleneck clams, an intense dose of garlic, olive oil, oregano, and grated Parmesan atop a charcoal-colored crust. The advanced move? Clam pie with bacon. Just expect to wait in line if you get there after 11:30 a.m. on a weekend.
