Grey Ghost Detroit shared by @eater says: ""Whether it’s a dry-aged steak or a patty, Grey Ghost's kitchen has a way with beef. This burger is definitely a step up from the typical burger stand meal, but the preparation is classic with two griddle patties layered with melty slices of American cheese, chopped lettuce, and special sauce with mayonnaise and onions. Putting an egg on it takes the whole experience to another level. And if that’s not enough, a Grey Ghost spinoff devoted to the beloved burger is heading to Ferndale. Make a reservation at the Brush Park spot through Resy."" on Postcard
