I arrived early at Don Muang Airport and had to fly again out later from Don Muang Airport. So I was hungry and in the mood for a good & comfortable breakfast. I enjoyed a fantastic breakfast buffet at "Zeppelin" Restaurant at Amari Don Muang Hotel. The hotel is located directly opposite the airport and there is a walking bridge between the airport and the hotel. And if you would arrive by train you can just walk to the hotel. Very easy and convenient. See Breakfast at Amari Don Muang Hotel
