Breakfast options are slim at 6am in terminal 4. I went for the becon egg and cheese on a croissant. Hard to screw up this classic and I was not disappointed. The croissant was lightly toasted and there just a small amount of yolk running out of the egg. I skipped the Sriracha mayo and did some hot mustard instead. All in all, a good sammich for a good price (considering it's an airport location ).
