Slow-season email offering a private event package to local businesses

During your slowest month, email a list of nearby offices, real estate agents, and event planners you've served before with a private dining or event package for that month, including a flat price per person and available dates. Follow up by phone with anyone who opens the email but doesn't reply within a week.

Why it works: Filling empty dining room hours with a private event brings in a full room during the exact stretch you'd otherwise sit empty.
