The best fast food restaurants in America

1. In-N-Out

The'secret' menu at In-N-Out isn't really a secret; the California chain even has a page for it on its website. But the not-so-hidden items still have a cult-like following among people who go out west to eat smashed burgers and animal-style fries.

2. Shake Shack

For some people, Shake Shack is both a fast food place and a restaurant they look forward to going to. If you want to eat slowly in one of New York City's most beautiful parks, make the line at its old site in Madison Square Park.

3. Popeyes Louisiana Kitchen

People, it's all about the spice. Popeyes' hush-hush blend adds Cajun flavor to many of its popular meals, like the famous fried chicken, creamy mashed potatoes, and those really salty fries.

4. Raising Cane's

In recent months, people have been most interested in fast food chains that serve chicken. And none of them are growing as fast as Raising Cane's, which began in the 1990s in Baton Rouge, Louisiana.

5. Zaxby's

When it comes to fried chicken, Zaxby's is one of the best—at least in the South. Two childhood friends came up with the idea for the comfort food spot on a basketball court in Statesboro, Georgia.

6. Taco Bell

Taco Bell doesn't seem to be slowing down; it seems like they add a new item every week. Even its bars that serve alcohol are continuing to grow. But even with all the new features and twists on its Mexican fast food, one thing stays the same: a stoner-friendly atmosphere.

7. Burger King

Just two words: flame roasted. This is the way that Miami-born Burger King has been known for its food since it first opened in 1954. Some burger chains use fresh toppings, and this one was one of the first to offer plant-based options.
