Frequently asked questions

What revenue should I target for fast-casual in Lille?

For a 40-80 m² unit with 20-30 seats, target 180K €-380K € € in year 1, scaling to 1.2-1.4x by year 3. Typical mix: 60-70 % dine-in, 20-30 % takeaway, 10-20 % delivery.

Which cost lines should I optimize first?

Food cost (32-38 % of revenue), payroll (22-28 %), delivery platform commissions (12-18 % on delivered share). Daily waste discipline and automation (kiosks, QR-code ordering) are the biggest margin levers.

Is delivery profitable for fast food in Lille?

Delivery via Uber Eats, Deliveroo or Just Eat adds 15-30 % revenue but cuts gross margin (25-35 % platform commissions). It is profitable if delivery ticket exceeds 12 € €, the menu is delivery-friendly (no fragile dishes), and packaging stays below 4 % of revenue.

Which legal structure to start with?

Solo founder: single-member LLC. With partners or investors: standard LLC or simplified joint-stock company. Sole-proprietorship status is only viable for micro-operations without commercial premises.
