Shake Shack is a popular fast food chain on the East Coast. I think the reason his burger is delicious is because the meat is so juicy and the special sauce is so appetizing. In addition to burgers, Shake Shack's unique jagged chips are also popular. Hot dogs, milkshakes, etc. are also worth trying. Look at the menu in advance to think about what to order, after ordering will get a small device that can vibrate, and when your meal is ready, it will vibrate and remind you to pick up the meal.
