This afternoon, Apple CEO Tim Cook took to Twitter regarding updates to the lunchroom at the company’s spaceship headquarters.

Cook’s tweet includes a GIF that demonstrates the very cool, ginormous sliding doors that slide open. The tweet reads “Lunchtime at Apple Park just got a whole lot more exciting 👀”.

Seeing those doors open is truly breathtaking as Apple has gone to the extreme in making these doors, which are made out of glass, span the height of the building, which is said to be roughly 3 stories high, and is curved.

The doors are typically only open slightly to let usual traffic through.

Check out the tweet below.
