It doesn't seem like there is another exit. In the scene where Dany leads them down there and locks them up, she uses that same door. When she leaves and rolls the stone back in front of the door, it shows the room getting pitch black.

That said, they don't show whether Tyrion/Varys close the door when they leave, so maybe they do leave it open for the dragons to leave and get food.
