One town south of me, in Bordentown, NJ, they've converted a bank into a pizza place. It's aptly called "The Vault". Good salad and pizza. Love the ambiance of the old building.
I once worked for a company in an old bank building.
There were vaults all over the place.
It was funny one had a huge vault door 4 feet thick at the front but 4+ smaller doors only a couple inches thick that were not directly visible from the front door.
They turned it into a data center along with the mainframe room and left the vault door as the main entrance.
