The listing is split into seven categories; the headings on the page read 単品ラーメン (ramen on its own), トッピング (toppings), 定食 (set meals), 単品 (other dishes on their own — the same 単品 as in the first heading), 飲茶 (dim sum), 飲み物 (drinks) and 調味料 (condiments). Each dish's allergen names are given beneath its name. Set meals come with the standard ramen, so the page asks you to check the entries for that ramen and any toppings you order as well as the set meal itself. Dishes served with cabbage also come with a dressing that contains wheat and eggs; the dressing itself is listed separately under 調味料 (condiments).

一覧は7つのカテゴリに分かれており、ページ上の見出しは「単品ラーメン」「トッピング」「定食」「単品」「飲茶」「飲み物」「調味料」です。商品名の下に、その商品に含まれるアレルゲン名が並びます。定食には基本のラーメンが付くため、定食の欄だけでなく、注文するラーメンやトッピングの欄もあわせて確認するよう案内されています。また、キャベツが付くメニューにはドレッシング(小麦・卵を含む)が使われており、ドレッシングそのものは「調味料」の見出しの下に別に載っています。
- Notes for reading
This page lists, under each dish's name, the allergen names it contains in parentheses (it is not a conventional HTML table). At the top of the page the chain states that it aims to mark an allergen as contained not only where its presence is clear, but also where it is shared at the processing or cooking stage — so the allergen names beside a dish do not necessarily mean the allergen is used as an ingredient. A note at the bottom of the page states that the listing covers the 28 items the Consumer Affairs Agency requires or recommends be labeled, but there is no per-item column and nothing says that an unnamed item is unused. We therefore treat any item not named against a given dish as unknown rather than assuming it is absent. (Japan's official list grew to 29 items in April 2026 with the addition of pistachio, but this page's note still refers to the older 28-item count.) Twenty-three dishes also carry the generic word 魚介類 (seafood). The page never explains what that word covers, and it is not the page's way of naming any particular item: a reader looking for shrimp, crab, mackerel, salmon, squid, abalone, salmon roe or anything else cannot take 魚介類 to stand for it. The page is not consistent about it either: ten dishes list 魚介類 alongside shrimp, crab or mackerel by name, while two dishes name mackerel or shrimp with no 魚介類 at all. A line that says only 魚介類 therefore tells you nothing about whether shrimp, crab or any other named item is present. We do not read 魚介類 as any particular item. Where the page names an item outright — shrimp, crab or mackerel, for instance — we read it as named; where a line carries only 魚介類, we treat every item that word could cover as unknown.

このページは商品名の下に、その商品に含まれるアレルゲンの名前をかっこ書きで列挙する形式です(通常のHTML表ではありません)。ページの冒頭には、来来亭は含有が明らかなものだけでなく、加工・調理の段階で共有するものについても「含まれる」という認識で表示するよう努めている、と書かれています。つまり、ある商品に並んだアレルゲン名は、原材料としての使用だけを指すとはかぎりません。ページ末尾には「消費者庁が義務・推奨表示の対象とする28品目について掲載している」との注記がありますが、品目ごとの欄がなく、名前が挙がっていないことが「使用していない」を意味するとはどこにも書かれていません。そのため当サイトでは、ある商品の説明に名前の挙がっていない品目は、含まないと決めつけず「不明」として扱っています(消費者庁の分類は2026年4月にピスタチオが追加され29品目になっていますが、この注記は従来の28品目のままです)。なお、23の商品には「魚介類」という記載があります。これは特定の魚介(えび、かに、さば、さけ、いか、あわび、いくらなど)を名指ししたものではなく、この語が何を指すかをページは説明していません。書き方も一定ではなく、「魚介類」と「えび」「かに」「さば」が同じ行に並ぶ商品が10ある一方、「さば」や「えび」だけが書かれて「魚介類」の付かない商品も2つあります。したがって「魚介類」とだけ書かれた行から、えびやかになど個別に名前のある品目が入っているかどうかは判断できません。当サイトでは「魚介類」を特定の品目に読み替えません。「えび」「かに」「さば」のように個別の品目名が挙がっている行は、その名前のとおりに読みます。「魚介類」としか書かれていない行は、その語が指しうる品目をすべて「不明」として扱っています。

Allergy notes
The official site publishes the allergens contained in each dish, based on the 28 items the Consumer Affairs Agency requires or recommends be labeled. Rairaitei says it aims to mark an allergen as contained not only where its presence is clear, but also where it is shared at the processing or cooking stage. Ordinary cooking equipment and tableware are shared across dishes, so even the smallest traces of an allergen may get into a dish during cooking or plating. Dishes are also made on equipment shared with other products that contain eggs, milk, beef, sesame, mackerel, banana, apple, pork or gelatin. Some dishes carry the word 魚介類 (seafood), which names no particular item; the page does not say which items it covers. The chain says that sensitivity to allergens varies widely from person to person, and that depending on the severity of a person's symptoms and their condition on the day, even a trace amount can bring on a reaction; it asks that this information be treated as a guide only and that the final judgement be made in consultation with a specialist physician.

公式サイトで、商品ごとに含まれるアレルゲン(消費者庁が義務・推奨表示の対象とする28品目)を公開しています。来来亭は、含有が明らかなものだけでなく、加工・調理の段階で共有するものについても「含まれる」という認識で表示するよう努めているとしています。通常の調理器具・食器を他のメニューと共用しているため、調理や盛り付けの過程でアレルギー物質がごく微量混入する可能性があります。また、卵・乳成分・牛肉・ごま・さば・バナナ・りんご・豚肉・ゼラチンを含む他の製品と共通の設備で製造しています。一部の商品には「魚介類」という記載がありますが、これは特定の魚介を名指ししたものではなく、どの品目を指すのかは示されていません。チェーンは、アレルギー物質への感受性には個人差が大きく、症状の程度やその日の体調によっては微量の混入でも発症する場合があるとして、この情報はひとつの目安とし、最終的な判断は専門医に相談するよう案内しています。
