  5. What to charge for restaurant in Illinois

    Menu built to a target prime cost (food + labor) under 60% of sales, food cost 28–35%. Average check and table turns per night are the numbers that decide viability, not just headcount. Check what the established restaurant businesses in your city actually charge before you set your rates — pricing to undercut them is the fastest way to work the first year at a loss.

  6. Getting your first restaurant customers in Illinois

    A strong soft opening, Google + reviews, third-party delivery apps, and local press. Prime cost (food + labor as a % of sales) makes or breaks a restaurant — target under 60%. The first 90 days set your local reputation. Local, weather- and season-sensitive, and heavily reputation-driven in the first 90 days. Google reviews, a strong soft opening, delivery-app presence, and local press set the trajectory.

  7. The mistake most first-year restaurant owners make

    Signing the lease before running the numbers on prime cost and break-even covers. Location and buildout excitement sinks more first restaurants than bad food — know your nightly break-even before you sign.
