If you can make better food than your competitors, you'll thrive
I have a couple of friends who have opened and run their own restaurants - there is an awful lot more to it than that and most restaurants fail for reasons that are nothing to do with the capabilities of the chef.
Sure. You currently need to be good at the many different things that make up running a business. But as the non-chef aspects (like your website and advertising, and hiring delivery drivers) become commoditised, that becomes less true.
Universally websites for restaurants suck. That’s why Uber eats is gaining so much market share (also the fact that they have given me over 100$ of free food this year). So it’s partially being better but also a whole shitload of load dumping or equivalent.
