About Quilo

Quilo helps you put a price on the fish before you order it. It combines a free fish-price calculator, a bill checker and practical restaurant phrases, with guides focused on Portugal’s Algarve and notes for coastal Spain.

Use the restaurant’s own price and the weight of the fish you choose. Quilo does the arithmetic; the restaurant confirms what your order includes.

How the calculations work

The calculator multiplies your entered price per kilogram by your entered weight in kilograms. Exact results round to cents. Portion mode applies Quilo’s stated raw-weight ranges and shows whole-euro estimates. Those presets are planning assumptions, not nutritional recommendations or a guarantee of portion size.

The bill checker compares that calculation with the amount charged. Its fish-line “matches” label allows up to €2 or 2% of the expected fish cost, whichever is larger. This threshold is a product choice, not a legal allowance. The difference is still shown to the cent.

Neither tool verifies a restaurant’s scales, current prices, freshness, included sides or whether a charge is lawful. Confirm those details with the restaurant. Photo reading can misread a board: check the extracted number before using it.

Editorial policy

• Make the evidence visible. Link factual consumer guidance to official sources and identify the country it covers. Practical suggestions and example calculations are labelled as such.
• Keep claims within their scope. Area pages describe geography and questions to ask. They are not inspections, restaurant reviews or endorsements of named businesses. A location alone does not establish price or quality.
• Use meaningful update dates. Dates on reviewed pages record substantive content changes. They do not mean a restaurant was visited, and a site deployment does not refresh every article’s date.
• Distinguish examples from live offers. Example host properties remain labelled examples. Unavailable services are described as unavailable; no booking or paid product is activated by these guides.
• Keep commercial links identifiable. Any affiliate link must be disclosed where it appears. An affiliate relationship is not evidence that a restaurant or service has been checked.

The calculator and bill checker have English, Portuguese and Spanish interfaces. The phrase cards show all three languages. Long-form guides are currently in English and carry English language markup. Quilo does not claim professional translation certification or legal review.

Sources behind the current guidance

The five main landing pages were reviewed on 21 October 2026. The review checked the calculations, removed unsupported blanket claims and linked the following primary sources. Check the linked guidance for its full scope and any later changes.

• Portuguese Directorate-General for Consumers (DGC) and AHRESP: restaurant rules and good practice (PDF, September 2023) — price lists, couvert and tap water, pages 9–12.
• ASAE: restaurant pricing questions — Portuguese displayed prices and complaints.
• Spain’s Law 7/2022, Article 18.3 — the requirement to offer free non-bottled water to customers.

Corrections and review

For editorial questions or corrections, email hello@lvgrv.co.uk.

Corrections should identify the page, the statement that needs changing, the country concerned and a supporting source. Consumer-rule corrections should be checked against the relevant authority; a single restaurant experience does not establish a rule for a whole region.

Correction, 21 October 2026: the phrases page previously said restaurants in Portugal and Spain could refuse tap water as a general right. That was incorrect. The page now links the applicable official guidance. The couvert guide also distinguishes food that was not requested from food that was consumed or made unusable, including opened packaging.
