Bomb Shelters / Bunkers?

Can someone point me to some really nice nuclear / bomb shelters? I’ve been trying to make my own but I wanted some inspiration and something to play around in for the meanwhile.

gm_safety_bunker was neat but it’s just missing something. Many ‘bunker’ maps are just bland halls and big open rooms with nothing in them.

Fellow Facepuncher Kefir just happened to venture into a Russian bomb shelter not too long ago, and he documented it quite well here.
