There was a Tx-style BBQ place I frequented that went through at least 4 ownership changes over 20+ years. Each new owner kept the staff and paid for the recipes- smart, because the place was ALWAYS lines-out-the-door busy at lunchtime, and none of the successors were even Americans. (3 different Korean families & one Egyptian guy with a silent partner.)
Every incarnation, the transition was virtually seamless. The Egyptian guy wanted to expand the menu, but he did so very intelligently: he started offering daily specials.
A year into that version, though, the Silent Partner decided he wanted to own an Asian restaurant. He closed the BBQ joint, replacing it with an Asian buffet. 6 months later, that buffet shuttered.
I want the Silent Partner’s idiocy to be clear: not only did he kill a thriving business, he didn’t have to do that to try out his idea. There were at least 2 other empty restaurant suites in the same strip mall.
Imagine going into the bank and talking to a loan officer. You’re launching a new Asian buffet. The banker asks about loan collateral and restaurant business experience, and you tell them you own a 20+ year old successful BBQ business…that you’re going to replace with the buffet.
