Which item on the menu is likely to be loaded with toppings like sour cream and cheese?

The Loaded Baked Potato is the item that is typically served with a variety of toppings, such as sour cream, cheese, bacon bits, and chives, making it a hearty and indulgent side dish. This dish is designed to cater to those who enjoy a rich combination of flavors and textures, as the potato serves as a canvas for these toppings.

In the context of the other menu items, the Classic Burger may come with a few basic toppings but does not emphasize an array of enhancements like the Loaded Baked Potato. The Garden Salad and Grilled Chicken Salad focus more on vegetables and are typically lighter in nature, lacking the rich combinations of toppings that define a loaded baked potato. Therefore, the primary characteristic of the Loaded Baked Potato as a dish that is "loaded" aligns perfectly with the question, establishing it as the correct choice.
