Year after year, cities across America continue to surprise us with new, innovative, and downright awesome businesses.

This year we've already brought you the coolest new businesses in PhiladelphiaChicago, and San Francisco, and now we've gone nationwide, finding the hottest restaurants, boutiques, startups, and everything in between across the U.S. 

There's a corner store with a bike-through window, a mobile shop that sells vintage clothing from a 1960s trailer, America's first pizza museum, and a Chinese restaurant that serves dumplings that look like Pac-Man characters.

Some of the businesses are based in brick and mortar stores, while others—like food trucks and mobile shops—sell their wares on wheels. We've also included several online-only businesses.

From San Francisco to New York (and everywhere in between), we've found the coolest new businesses in America that opened or expanded within the last year and a half. Email MNisen@businessinsider.com if we left off your favorite.
