McDonald's has designed a brilliant new take-out bag that turns into a tray. 
The BagTray was developed by McDonald’s Hungary and ad agency DDB Budapest, Gizmodo reports.
Pulling a strip of paper near the bottom of the bag detaches the tray, which is made from reinforced cardboard.
The tray acts as a plate, making it a lot easier to eat food on the go. 
We reached out to McDonald's to see if the trays would be available in the US and we'll update if we hear back.
