Understanding Portion Sizes and Meal Value

Use sensible portion comparisons and cost-per-person calculations without assuming bigger always means better.

Use sensible portion comparisons and cost-per-person calculations without assuming bigger always means better.

How to use this guide: Start with the restaurant’s own current menu and a basket that reflects the food you actually want. All examples are for explaining the method unless an official current source is explicitly linked.

Why portion comparisons matter

Two meals with similar prices can contain different quantities of food. For shared meals, the number of intended diners is often more useful than the total price alone. A larger bundle may have a lower price per person but still produce waste if the group is small.

Begin with actual appetites, dietary needs and the occasion. Then compare similarly sized choices where menus provide enough information.

Use published sizes carefully

Some menus disclose weight, volume, piece counts or suggested number of servings. Others use descriptors such as regular, large or sharing without a standard definition across brands.

A “large” at one restaurant is not necessarily equivalent to a “large” elsewhere. Avoid claiming a cost per gram where the weight has not been verified.

A clear worked example

Suppose a hypothetical £18 sharing meal is suitable for three people. Dividing £18 by three gives £6 per person. If it only satisfies two people, the actual cost per satisfied diner is £9. The quoted price itself did not change; the realistic number of servings did.

For individual meals, compare whether a side or drink is already included before adding them to your final estimate.

Think about more than price

Value can involve convenience, flavour preferences, nutritional suitability, portion size, accessibility and how much of the meal will actually be eaten. Cheaper is not automatically better for every person.

Use money comparisons as one decision aid. Do not ignore allergen requirements or personal preferences to optimise an equation.

Plan with actual quotes

Take current prices from the restaurant’s official site or checkout. Enter the quantities you expect to buy into the AllMenus cost calculator and assess a few practical baskets.

If the exact quantities or prices are missing, label the outcome an estimate rather than presenting it as a verified restaurant price.

Put it into practice

Choose the relevant official restaurant menu from our directory. Note the branch, ordering channel and specific products, then use the meal budget calculator or two-quote comparison to test your choices. For allergen needs, check the restaurant’s official information and speak to staff.
