Vintage photos show what it was like to eat at Burger King in the 1980s

After opening its first location in Jacksonville, Florida, the chain quickly grew to become the second-largest fast-food chain in the country, behind McDonald's. The chain now consistently ranks among the top 10 biggest fast-food chains in the world.

An early version of the Burger King logo featured curved letters sandwiched between two yellow buns.

The chain is now using a very similar logo that embodies the same nostalgic, vintage feel. 

Drive-thrus proved to be an essential element for the success of fast-food chains.

According to Encyclopedia, drive-thru sales accounted for 60% of fast-food sales by 1987.

While many menu items like the Whopper, fries, and burgers that customers were able to customize and "have it your way" are still on the menu today, Burger King restaurants in the 1980s also had a customizable salad bar.

Burger King's uniforms have changed drastically during the chain's lifetime. In the 1980s, the brand started experimenting with plaid, stripes, and baseball caps, Business Insider previously reported. 

In this image from 1983, Burger King University Dean Al Jesness shows an employee how to fill a soft-drink cup. As the company grew, the university in south Miami was where Burger King's managers went "to learn the holy grail of the perfect burger," UPI reported in 1983.

The Whopper, which was released in 1957, cost 37 cents compared to Burger King's original burger, which cost 18 cents. The Whopper came with sauce, cheese, lettuce, pickles, and tomato, all piled on top of a larger patty.

Today, Burger King still broils and flame-grills its burgers.
