Gustavo Arellano Promotes New Book, 'Taco USA' On 'Chelsea Lately' (VIDEO)

Mexican writer and HuffPost blogger Gustavo Arellano made an appearance on "Chelsea Lately" this week to promote his new book "Taco USA: How Mexican Food Conquered America".

"Here in the United States, we combine the best of both worlds, the Mexican and the American, into creating baroque dishes with a timeless quality. But the United States is also an area where Mexicans forgotten in Mexico have been able to assert themselves with their own unique cuisine, frequently finding fans among Americans unlike in Mexico, where their culinary treasures wouldn't have been able to get them arrested. It's in the United States where Mexican food truly shines," Arellano wrote in a blog for The Huffington Post.

Even if Chelsea thought Gustavo was a chef rather than a writer at first, we were proud to see him do his thing on late-night TV. Chelsea's assistant "Chuy Bravo" also gets in on the fun, correctly guessing that Puebla is in the country of Mexico.

Here are some of Gustavo's favorite Mexican restaurants in the U.S.:
