Its broad, boldly marked red and black beak and orange legs contrast with its plumage. It moults while at sea in the winter and some of the bright-coloured facial characteristics are lost, with color returning again during the spring. The external appearance of the adult male and female are identical though the male is usually slightly larger. The juvenile has similar plumage but its cheek patches are dark grey. The juvenile does not have brightly coloured head ornamentation, its bill is narrower and is dark-grey with a yellowish-brown tip, and its legs and feet are also dark. Puffins from northern populations are typically larger than in the south and it is generally considered that these populations are different subspecies.

The menu consists of tacos with American fillings, and did not sell food sold in Taco Bell restaurants such as burritos. It was launched in Huntington Beach, California in August 2014. U.S. Taco Co. closed on September 15, 2015 so the company could focus on its new similar Taco Bell Cantina concept, which featured special menu items and served alcohol. It opened its first location a few days later in Chicago's Wicker Park neighborhood, followed by a location in San Francisco about a month later, located less than a block away from AT&T Park. In 2016, Taco Bell launched the Taco Bell Catina flagship store located on the Las Vegas strip. This 24-hour restaurant hosts a variety of unique features including alcohol, new menu items, and a DJ. It was announced in August 2017 that the store would begin hosting weddings. Taco Bell Cantina currently has locations in San Francisco, Berkeley, Chicago (2 locations), Las Vegas, Austin, Fayetteville, Cincinnati, Cleveland, Atlanta, Newport Beach, and plans to open soon in Somerville, MA.
