This post isn't about fast food places. It's about overpriced local shops that sprung up in the formerly "bad" part of town and are run usually by <30 year olds with no business experience. Give me your hometown and I promise I can find one of them online for you to go to
To be fair tho I live in Chicago and there's 2 of these places by me. But there's another 2 that I can get a loaded combo with fries and a drink for about $10 USD and it's always fresh and delicious.
No link but American wild burger, the one in the city shut down apparently but there's still one in the suburbs. Add bacon cheese and BBQ sauce and you're at a little over $20 for a burger with no fries.
If you go to Google maps and just type burgers and filter price $20+ or $30+ there are plenty burger bars that will match that criteria.
