A little about Smashburger
Smashburger's signature cooking technique involves "smashing" the burger patty onto a hot griddle, which creates a caramelized crust and enhances the flavor. The menu typically offers a variety of burger options, including classic cheeseburgers, specialty burgers with unique toppings, and vegetarian or chicken alternatives. They often provide customizable options, allowing customers to choose their preferred toppings, buns, and sauces.

In addition to burgers, Smashburger typically offers sides like fries, onion rings, and milkshakes. Some people appreciate the variety and quality of these menu items.
