What is stated about severe allergies

Differences between stores
We have not yet established whether things differ between stores. That is not a statement that they do not.
As a Skylark Group-wide notice, some individual stores may not provide allergy information, so it may not appear in the table; store-by-store differences specific to this brand could not be confirmed from this page.(machine translation)

- Notes for reading
The table's marks are a strict binary of 'contains' / 'does not contain' — incidental trace cross-contact is not accounted for or shown. Sauce-bar items, table condiments, customer-chosen sauces/dressings, the drink bar, and alcoholic drinks are outside the table's scope (many individual item names also state their own exclusions). Buckwheat-containing items share cooking equipment and boiling pots with other noodle dishes, and shrimp/crab may be incidentally present in some seafood due to harvesting method or natural cohabitation with shellfish. This table only covers the 9 items Japan classifies as mandatory-labeling allergens — the further 19 recommended items have no column at all here, so nothing can be inferred (safe or otherwise) about those items from this table.

表の記号は「含む」「含まない」の二値のみで、意図しない微量混入(コンタミネーション)は考慮・表示されていません。ソースバー、卓上調味料、お客様が選ぶソースやドレッシング、ドリンクバー、アルコール類はこの一覧表の対象外です(多くの商品名にも個別に除外範囲が明記されています)。そば粉を使う商品は他の麺料理と調理器具・茹で釜を共有しており、えび・かには漁法や貝との共生により意図せぬ混入があり得るとされています。この一覧表が対象とするのは『特定原材料』とされる9品目のみで、それに準ずる19品目は対象外(列自体が存在しない)のため、その19品目については安全とも不使用とも読み取れません。
- Legibility notes
The table page can only be reached by stepping through the brand-selection and usage-type screens first, but the content itself is plain HTML text, not an image.

Allergy notes
For the eat-in menu, the official 'Skylark Group Allergen Search' site provides an item-by-item table. It covers the 9 allergens Japan classifies as mandatory-labeling items (buckwheat, peanut, wheat, egg, milk, shrimp, crab, walnut, cashew nut); the additional 19 recommended items are not disclosed for this brand. Sauce-bar items, table condiments, customer-selected sauces/dressings, the drink bar, and alcoholic beverages are outside the scope of the table. The table only shows a binary 'contains' / 'does not contain', and does not reflect incidental trace cross-contact that may occur during factory or in-store cooking and plating. The chain notes that buckwheat-containing items share cooking equipment and pots with other noodle dishes, and that shrimp/crab may be incidentally present in some seafood due to harvesting methods or natural cohabitation with shellfish.
