We have a special clay oven in the back, you know, and we have around this glass people can watch how we make the chicken tandoori specially, also the bread called naan bread.

Each window also gets coated with a thin Mylar film that and is then baked in an oven that stretches the UV-retarding material tightly against the glass, removing any visible imperfections.

The cake would come out of the oven and everyone would be ready with a glass to prop underneath, careful not to Pierce the top of the cake.
