Things to Consider When Opening a Part-Time QSR (5 PM – Midnight)

Has anyone here worked a full-time day job while building a part-time QSR business in the evenings (starting at 5 PM)? I’d love to hear your insights — what worked, what didn’t, and what you wish you knew before starting.

What should I think about? What should I do? What should I avoid?

Thanks in advance!
