How to turn a fallout shelter into a business?

I have the chance to lease a bunker—basically an old tunnel—to launch a profitable venture, and I’m looking for ideas on how to actually utilize the space. I considered mushroom farming, but the lack of electricity and running water makes that a massive hurdle, even if I could figure out a way to get utilities in. Hospitality is off the table for now. I did read something about vermicomposting with California red worms, but I'm completely in the dark on that one. HELP!

don't even bother asking me about it, just hit up Google; I'm sure you'll dig up plenty of stuff on your own.

So I stumbled into this bar in New York City... From the street, it looked totally uninspiring—just your run-of-the-mill, average-looking joint, maybe even a bit of a dump...

But then I hit the stairs leading down to the basement... And man, it was intense. Low ceilings everywhere, like you’d been shoved into some half-empty wine bottle filled with dirt. At its highest point, the ceiling barely cleared five-foot-seven. Everything felt cramped, with these old, beat-up chairs and tables, lit by just a handful of candles.

The menu there is strictly wine and cheese—stuff sourced from all over the map. The prices? Yeah, they'll sting, but the vibe is unbeatable. Honestly, it goes without saying that I ended up going back there more times than I can count.

It would be killer to open something like that here, though everything really hinges on what kind of shelter you're working with. Mind you, the spot in New York wasn't even a fallout shelter; it was more like some ancient catacomb from God knows when.

Unforgettable.

Do some digging into what they’re doing over in Albania with tens or even hundreds of thousands of identical ones.

I’m just recounting this, but...

A buddy of mine was out in Chicago a little while back... they took him out to dinner at this warehouse... at first, he honestly thought they were playing some kind of prank on him because the whole place looked like a totally derelict, abandoned warehouse...
And let me tell you, these warehouses are massive—just crumbling, run-down spots straight out of a gritty crime movie where all sorts of shady deals go down...
But inside one of them, they’ve built this restaurant. And I don't mean they renovated the space, either; they basically dropped a glass... how should I put this... 🤔 cube right into the middle of it. Inside that glass enclosure, the restaurant is designed to blow your mind—the food is absolutely killer. You're sitting there looking through the glass at this warehouse that looks like it could collapse at any second... but the vibe and the meal? It's 👍 incredible

You guys just won't stop harping on about cafes and restaurants, even though the guy laid it out perfectly well:

the hospitality industry is basically off the table right now

it’s like you all can only think of coffee shops when it comes to business ventures.🙂

I really hope I don't get banned for this (seriously, delete me if you have to), but I am absolutely losing my mind if I don't get this off my chest:

Oh, look at this... all the mods are hanging out together, and now we’re just missing Vojko 😍

Lipo, I’ve seen those lipo videos myself back when I was out working, but you need a mountain of cash for that—and even more people willing to blow it all at my place. And that... well...
Any experts in here know anything about, say, worms or breeding some kind of creature that doesn't require daylight? Thanks, guys.
