Celebrate with a Sazerac: New Orleans was ranked the second-best city in the country and No. 7 in the world in Travel and Leisure’s annual readers’ poll.

This marks the third straight year that New Orleans was named the No. 2 city in the U.S. This year, it finished behind Charleston, South Carolina, which also ranked as the No. 1 city in the world.

Now in its 21st year, the survey asks readers to rank cities based on sights and landmarks, culture, cuisine, friendliness, shopping and overall value.

“It’s an incredible honor to be recognized as one of the top 15 cities in not only the U.S., but the entire world,” said Stephen Perry, president and CEO of the New Orleans Convention and Visitors Bureau.

Perry credited New Orleans’ “rich history, unmatched Southern hospitality and unrivaled authenticity” for its high rankings.

The travel magazine’s readers also voted the Old No. 77 Hotel & Chandlery, which opened last year in the Central Business District, as the No. 7 city hotel in the continental U.S.
