I know he's frustrated, as anyone would be, but the deck was stacked from the get go and it's no one's fault but his. Not the landlord or the grease trap. That was writing on the wall about unknown unknowns.
He starts by saying how "hot" the market is, like that's a good thing for his persuit. He starts with talk of it being saturated. The landlord doesn't need to take any risks on that hot corner for your grease trap or electrical.
I've taken a bath on a few things where I over invested in fixed costs. I've had to take a couple years off after a six year startup struggle because of burnout. I will say that when I've come back around, after really fucking kicking myself and licking all wounds, it was a VERY expensive lesson. Emotionally, fiscally, and socially. Usually cheaper than a masters degree though and infinitely more applicable to future runs at the real goal.
You want to get free and run a creative operation? Great. The world does not give a shit. Worse than that, it hates you and wants you to fail. The path to real freedom is paved with bloody miserable failure. Bad leases will eat you, which is not the landlords fault. If you want to make money, buy a Chick-fil-a franchise. They have a great track record and financing. If you wanna make art, be prepared to suffer for it and have no one give a flying fuck about how much it hurt to try.
The desire to blend art and commerce is something that very few people succeed at. Just because you have worked in a kitchen and scored a half million in inheritance doesn't mean anyone needs to care. No matter how much you spent. You could have put the cash in an account and get so good at cooking that someone else will take the ops risk to open your counter or take the risk yourself and learn hard what you don't know. The world sheds no tears either way.
Bunk Sandwiches in Portland didn't start with a $40 chicken. They started with a hole in the wall and a Cuban Sandwich that would make you slap your grandma. Also they could make them fast for $12 and had a line out the door. Eight years later they have several locations and a concert venue. The sandwich isn't as good anymore, but they made a legacy out of thing that could support itself and can continue to grow. I don't know anything about their owners, but I bet they can tell you some shit about surviving upside down leases and kitchen costs.
I seriously wish this guy the best. I'm sure some days that chicken was one of the best things anyone has ever tasted.
