Shake Shack Incheon Airport Terminal 2 is a burger restaurant on the third floor of the departures area at Incheon Airport Terminal 2. The Shake Stack comes with a fried mushroom patty and cheese, and milkshakes and fries can be ordered alongside it. Luggage can be stored in front of the store, which makes it convenient to stop by before departure. Food can take around 30 minutes to come out after ordering, so allow plenty of time before your flight.
