Here are four stats on our burger-eating habits, according to a survey of 1,000 Americans:

1. Our favorite burger topping is cheese. 79% of Americans like it on their burgers. The rest of the top five are lettuce, 71%... tomatoes, 66%... onions, 58%... and pickles, 54%. They didn't ask about condiments for some reason.

3. Our five favorite burger chains are McDonald's, Five Guys, Wendy's, Burger King, and Steak 'n Shake.

4. And according to the survey, the five cities that love burgers the most are Seattle, Philadelphia, Boston, Baltimore, and Miami.
