Definitely from someone else with a successful entrepreneurial career in food.
1. You need "smart money," not just money. My wife was an entrepreneur in food for 8 years and did it herself. The amount of bizarre stuff that happens there is unthinkable. Having someone to help see around corners is a secret weapon you want to have.
2. You need someone who understands the mechanics of the business, who understands that turnover every three months in delivery drivers and dishwashers screwing the hostesses in the alley is nothing to worry about. Who understand the pay-back periods and the labor of love.
