The Big Mac has been served at McDonald's restaurants since 1968. A franchisee invented it and sold it for a whopping 45 cents back in the day in an effort to compete with the burgers available at Bob's Big Boy restaurant. Looks like they succeeded.

The Whopper is the signature burger of Burger King and is often positioned as the BK version of the Big Mac. Interestingly, the Whopper predates the Big Mac by 11 whole years, so technically, is a Big Mac the McDonald's version of the Whopper?

The Meatball Marinara has been a staple at Subway for years and is one of the few menu items that you're going to get hot no matter what, while most of the menu can only be warmed up when toasted. It's also one of the few subs that's generally complete as is—unless you want to add lettuce or mayo to it! You do you.

Wendy's Baconator was a huge success for Wendy's when they introduced it to appeal to 18- to 24-year-old burger fans. It's a half pound of beef and six slices of bacon, which makes it a bit more intense than your average bacon cheeseburger.

The McDonald's McChicken is their signature chicken sandwich and has been on the menu since 1980. It's actually been removed from the menu several times over the years to be replaced, first by Chicken McNuggets and then later by the Crispy Chicken Deluxe. Fan demand kept bringing it back, though.

The McRib is one of the strangest sandwiches on the McDonald's menu. Only available for a limited time every so often, it's a shaped patty of pork designed to look like a slab of ribs even though it has no bones in it. Poor sales removed it from the menu originally, but McDonald's managed to make it a success by making it a rarity.

Arby's has existed since 1964, and the chain has always been a sandwich shop. Originally, all they sold was plain roast-beef sandwiches and chips at a premium compared to hamburgers. Within a decade or so, they innovated to add cheese to the sandwich, because roast beef is always better with cheese.

The original McDonald's Hamburger was one of only a handful of items on the McDonald's menu when the restaurant first opened. There were two burgers on the menu—a regular hamburger and a cheeseburger—and most of the rest was actually just drinks like Orangeade and coffee.

A Chick-fil-A chicken biscuit is part of the breakfast menu and features a seasoned breaded chicken breast on a buttermilk biscuit. Not a lot to it, of course, but every company wants to cash in on the breakfast rush.

A&W has had a strange history as a restaurant chain: At one time, it was actually bigger than McDonald's, but some business problems caused the company to suffer a few setbacks over the years. These days, they're mostly known for their root beer and the classic Papa Burger.

The Jumbo Jack is essentially the Jack in the Box version of a Big Mac or a Whopper. The franchise has actually been around since 1951, almost as long as McDonald's has existed, meaning the Jumbo Jack grew up alongside the Big Mac.

The Checkerburger is the burger to order when you hit up Checker's or Rally's drive-thru joints. It's a pretty standard burger overall, with lettuce, pickle, tomato and onion on a sesame-seed bun. They also serve it with mayo, ketchup and mustard. It's pretty great.

The McDonald's Quarter Pounder has long been the standard for "big" burgers out there and is simply labeled by its weight. Back in the day, A&W introduced a 1/3 pounder that was cheaper and tasted better, according to reviews, but sold poorly because a lot of people didn't understand it was actually bigger, not smaller.

Wendy's Spicy Chicken Sandwich is a marinated chicken breast breaded and seasoned with a pepper blend that gives it a bit of a zip. Most restaurants have a spicy sandwich on the menu, but Wendy's one is one of the most popular, outside of places like Chick-fil-A that specialize in chicken.

According to legend, the Filet-O-Fish was invented as a way to draw Catholics to McDonald's on Fridays, a day when they traditionally were prohibited from eating meat like beef. The Hula Burger, a pineapple slice on a burger, was an alternative as well that proved to be far less popular than the fish.
