yeah but do they elevate the consciousness of the universe?

That doesn't seem to match with the definitions I can find for commissary.

https://www.merriam-webster.com/dictionary/commissary

The idea of a 'cloud kitchen' or a 'ghost kitchen' is different from a commissary kitchen, and the terminology doesn't help make this distinction. 'Cloud restaurant' or 'ghost restaurant' would be more appropriate, as the "restaurant" is the ethereal part, not the kitchen. A commissary kitchen can act as the kitchen for a 'cloud restaurant', but the restaurant itself is more a product of branding and food curation that only lives in the minds of the creator and the customer, and this is enabled by decoupling the distribution channel from the production. Food trucks and caterers bring food directly to their customers, and usually have a more personal relationship with them.

They are not the same, but ghost kitchens do operate out of a commissary. A commissary is a shared use kitchen. A ghost kitchen (which admittedly would probably be better called a ghost restaurant) is basically just a delivery/pickup-only restaurant. It may operate out of a commissary or its own space.

The Food Corridor is a (very terrible) piece of software that allows bookings for kitchen space, so they probably focus on the ones that work from public kitchens for that reason, but lots of them have dedicated kitchens or rent from a church hall or VFW.
