The Big Chicken, an Atlanta landmark. Yes, the eyes and beak move.
Sometimes the easiest way to tell what a store sells is by looking at the shape of the store itself. Like a library shaped like a stack of books or a Burger Shack that's a giant burger, Shaped Like What It Sells is a building that is modeled and designed to look like the product(s) that's inside of it. According to The Field Guide to Sprawl, in Real Life, the name for this type of a building is a "duck," after a duck-shaped duckling stand. (The term was coined by architect Robert Venturi.)
Should a giant entity mistake it for the real deal, This Billboard Needs Some Salt will likely ensue.
A Subtrope of Bizarchitecture. Not to be confused with Shaped Like Itself. Compare with Exactly What It Says on the Tin.
There was a joke along these lines in one episode of How I Met Your Mother. Ted was designing a building shaped like a 10-gallon hat for some cheesy Texan Rib-joint franchise. Instead, they went with a Mecha-Godzilla shaped building (wearing a cowboy hat). No businessman is going to have a building design that needlessly complex if he's not going to sell souvenirs inside...unless, of course, he's been charmed by the powers of Sven.

In Space Quest 4, Monolith Burger does this, probably for laughs because it's a parody of McDonald's. You even have to work there to make money.
Fallout: New Vegas has two examples of this that can be found in the Mojave. The first is the Sunset Sarsaparilla factory that has a front entrance shaped liked a bottle of the titular drink. The second is the Dino Delight motel which has a giant Dinky The Dinosaur stature that doubles as a shop that sells small Dinky action figures as well as a few other things. Interestingly, both locations need to be photographed for a sidequest where an artist in New Vegas uses them for inspiration for making his own neon signs.
The main shops of Neopets are themed like this: The food shop is a hamburger, the book shop is a book, the auction house is a mallet, the post office is a postal parcel, the pizza shop is a pizza, the school supply shop is a pencil, the music shop is a tuba of sorts, health food shop is broccoli, the defence item shop is a helmet, the gift shop is a gift box, the bakery is a peppercake house, the collectible card shop is a cardhouse, the hot dog shop is a hot dog, and the chocolate factory has chocolate topping.
