Every year, Travel + Leisure mines through tens of thousands of World’s Best Awards surveys—in 2015, we received responses from 199,652 people from around the globe—to better understand where are readers love to go, and why. Of course, the responses say just as much, if not more, about what our readers don’t like.

We asked readers to rank 266 cities on everything from their value to the friendliness of their people: and some cities failed to warm tourists’ hearts. Not surprisingly, many of the cities that found themselves on our 2015 Unfriendliest Cities in America list (based on separate data from our annual America’s Favorite Places survey) were also called out in this census.

Here, some of our most-loved cities for cultures and the arts, or for wild nightlife and burgeoning food districts, show that even the best have room for improvement. (Want to see the cities that have already achieved excellence? Click here for our World’s Friendliest Cities list.)

Of course, we’ve all had an unfriendly encounter with a local, or caught a city that’s just woken up on the wrong side of the bed. We know these cities, at their best, can all be inviting, vibrant, and dynamic destinations.
