The chain is known for its square hamburger patties served on circular buns, sea salt fries, and the Frosty, a form of soft-serve ice cream mixed with starches. Wendy’s menu consists primarily of hamburgers, chicken sandwiches, French fries, and beverages such as Frosty. Since phasing out its Big Classic, the company does not have a signature sandwich, such as the Burger King Whopper or the McDonald’s Big Mac.

The company’s milestones:

November 15, 1969 – Dave Thomas opened his very first Wendy’s restaurant in Columbus, Ohio at 257 East Broad Street. In no time, the quick-service chain became known for its square beef patties, made from fresh beef, and iconic Frosty® desserts.

1970 – Wendy’s introduced the first modern drive-through to the world; what Dave Thomas coined the “Pick-Up Window”.

1975 – Wendy’s brought beef to Canada when it opened the first international Wendy’s restaurant in Hamilton, Ontario, Canada.

1977 – Wendy’s took its advertising to the small screen, making a name as the first quick-service chain with less than 1,000 restaurants to launch a national advertising campaign.

1979 – Among all the fresh beef, Wendy’s added the salad bar to its menu to diversify the options for those who wanted to go green with their meals.

1983 – Baked potatoes joined the menu in 1983. The Wendy’s baked potato saw success in the 80’s as the ever-memorable “hot-stuffed” and has stood the test of time as a tried and true favorite for customers seeking a lighter side or as a destination to accompany their chili.

October 1989 –  Wendy’s was the first to introduce the concept of a Super Value Menu and it took off with nine items available for 99¢ every day. The menu offerings rotated based on what customers were craving.

1990 – The grilled chicken sandwich made its first appearance in 1990 as a lighter, lower calorie offering for customers seeking a non-fried chicken protein option.

March 1992 – Born from Wendy’s successful and iconic salad bar, Wendy’s turned customers’ attention to new, fresh-made salads they could get to-go: Grilled Chicken, Taco Caesar, Deluxe Garden, and Side Salads were the first salad offerings featured.

July 2004 – Wendy’s rolled out kid-friendly offerings for its youngest customers called Wendy’s Kids’ Meal. At launch and for no extra charge, Mom and Dad could swap out French fries for mandarin oranges and grab some milk for their kiddos instead of a soda.

November 2004 – The new Wendy’s Combo Choices Menu proved that sides could be more than just French fries, and allowed customers to choose a baked potato, small chili, or one of two side salads instead of French fries.
