Taco Bell is currently one of the biggest fast food chains in the world. The restaurant, however, came from very humble beginnings, similar to many successful startups. Here is its very first menu.

According to the Huffington Post, the original Taco Bell started during the early 1960s as a last effort of food entrepreneur Glen Bell. A rare photo showed a no-frills menu board and the chain’s very first franchisee, Kermit Becky, in 1965. The list only consisted of six items:

• Frijoles – $0.19
• Tostados - $0.19
• Tacos - $0.19
• Chili Burger - $0.19
• Burritos (green sauce) - $0.19
• Burritos (red sauce) - $0.19

They also served Coca-Cola, orange juice, root beer and coffee at the time. All the food items were classic and cost $0.19. By the late 1960s, Taco Bell was reaching new business heights and the menu went through a number of adjustments as well. "Wild taco mashups" and the Bellburger followed. The Bellburger, which is a hamburger with taco meat, spicy sauce and cheese, was removed from the list in the late 1970s in lieu of the Bell Beefer. The Bell Beefer grew in popularity during the 1980s but was also taken out later on.

Huffington Post further reports that the same items from the original menu are still present, except for the Chili Burger. Tacos are still the top seller of the fast food chain while burritos are its second bestseller. Frijoles, described as beans and cheese, and tostados, which is now known as tostada, are still available today.

Grub Street revealed that Taco Bell also showcased its new mystery food item at Super Bowl 50. Dubbed the Quesalupa, the company described the product as its biggest food creation and most craveable innovation yet. It is actually a cheese quesadilla with the new product maneuver filled with ground beef. The item is essentially a Chalupa but filled with melted cheese within its puffy shell.

Overall, the outle notes that Quesalupa is consistent with Taco Bell’s objective of menu singularity, where tortillas, cheese and ground beef can be used in any way and offered for only $2 to $3. It also shows that the company has continued to build itself through the decades by keeping its menu simple and using the same basic ingredients that people love.

The original Taco Bell is currently located near the headquarters in Irvine, California, per the Huffington Post.
