VC is equity not debt, and very very few restaurants raise money via equity.
Often they'll take out large loans secured on both house and business, along with a chunk of their own (or investor/friends) money to get things started. The lenders get to stick nice chunky rates on the whole thing and generally have limited downside because collateral.
I don't mean to imply the banks are doing anything wrong, just that the business model is based on managed downside rather than "striking it rich"
Correct, but I would say it's next to impossible to find a VC who treats a SAFE/Convertible Note as debt. Nobody wants it paid off, the VC will always choose to convert to equity because that is the VC's model.
