The Restaurant Challenge

Two cooks on the same line will plate the same dish differently — by 10-30 grams, every time. Across a month, that drift adds up to lakhs in inconsistent food cost and customer experience. The cook who plates generously is liked by guests but kills your margin. The cook who skimps is cheap but generates complaints. Without standard portions, both your cost and your customer experience are uncontrolled variables.

Why This Matters

Portion control is the boring discipline that separates restaurants that scale from restaurants that struggle. Chains succeed because every portion is identical — across cooks, shifts, and outlets. Independents lose 4-8% of margin to portion drift without realizing it. Fixing this does not cost money. It costs a portion scale, a printed standard, and ten minutes of staff training.

Why This Matters

  • Cut 4-8% of invisible food cost from portion drift
  • Deliver consistent guest experience across shifts

  • Make portion size a measurable KPI, not a vibe

Frequently Asked Questions

For mains, ±5% of standard weight is acceptable. ±10% means the kitchen needs portion guides or retraining. ±20% means there is no standard at all — every cook is doing their own thing.
