Golden Chicken Burger is a food item originally designed for the KFC × Genshin Impact crossover event. It was available for a limited time in version 1.4 during the login event Outland Gastronomy.
In-game Description:
A hamburger in which the fowl meat is the main star. The fluffy bread sandwiches slices of fresh vegetables and a flavorful, crispy fowl fillet. No utensils required here: Just grab it in your hands and bite down on that bundle of rich, satisfying succulence with a hearty "ker-runch"!
