Overview
ISO 21621:2021 - Tourism and related services - Traditional restaurants - Visual aspects, decoration and services provides requirements and recommendations for the visual environment and service provision of traditional restaurants tied to a specific country, area or cuisine. It focuses on the physical and cultural elements that create an authentic dining experience - façades, interior decoration, furniture, table setting, menus and staff presentation - while explicitly excluding technical building characteristics and kitchen preparation/cooking requirements.
Key topics and requirements
- Visual specifications: facade design, harmonized signage, main hall layout, floor/wall coverings, use of natural or local materials, and preservation of historical character in converted buildings.
- Decoration and cultural authenticity: integration of cultural motifs, collections and period-appropriate furnishings to reflect the targeted traditional style.
- Table setting (mise en place): standardized presentation elements that support the traditional dining experience.
- Staff requirements: clothing, behaviour, language and qualifications that influence authenticity and guest satisfaction.
- Accessibility and facilities: level entrances or ramps, separate accessible toilets, tactile signage and braille, baby-changing facilities and appropriate sanitary fittings.
- Operational aspects: carrying capacity considerations, maintenance plans, waiting areas, staff-only spaces and waste/smoke collection systems.
- Safety, security and sustainability: ventilation, bioclimatic design elements and energy-saving smart technologies are encouraged.
- Scope boundaries: does not cover technical building characteristics or kitchen preparation/cooking processes.
