公式サイト 商品一覧(商品ごとのページにアレルゲンのアイコン表示)
Official site product list (each product page shows allergen icons) — This document does not state which items it covers (we have not confirmed a column for each item)
- Document size
Product pages on the official site. The product list is split into categories (standard items, limited-time items, etc.); each product's own page has an "allergy" section showing the allergens it contains as icons.

公式サイトの商品ページ。商品一覧はカテゴリ(定番商品・季節限定など)に分かれており、それぞれの商品の個別ページに「アレルギー」欄があり、その商品に含まれるアレルゲンがアイコンで示される。
- How menus are ordered
- Listed by category
- Notes for reading
The icons on each product's own page show the allergens that product contains, but the site does not state which allergens were checked to produce that display. So the absence of an icon for a given allergen cannot be read as "does not contain" that allergen.

個別の商品ページのアイコンは、その商品に含まれるアレルゲンを示すものだが、どの品目まで確認したうえでの表示なのかという説明は見当たらない。そのため、アイコンが付いていない品目について「含まれていない」と読むことはできない。

Allergy notes
On the official site's product list, each product page has an "allergy" section showing the allergens the product contains as icons (the croissant, for example, shows wheat, egg and milk). The pages do not state which allergens were checked, so the absence of an icon cannot be read as "does not contain".
Show the original
