- Notes for reading
This listing covers only the dine-in menu; takeout and delivery menus are shown on separate pages. It covers only the 9 mandatory items — buckwheat, peanut, wheat, egg, milk, shrimp, crab, walnut and cashew nut. The 19 recommended items the Skylark group discloses for some of its other brands (such as almond or soy) are NOT included in Jonathan's listing. Drink bar and alcoholic drinks are not covered by this site at all (it notes they use shared pour spouts). Items you choose yourself, and condiments used to taste such as soy sauce or Tabasco, are also outside the table. Cooking equipment, dishware, frying oil, coatings and ingredient storage areas are shared; noodle dishes including soba use the same equipment and pot, and the various hamburger steaks are made on shared equipment, so an allergen can turn up in a dish even where the table does not list it. Some seafood is caught using methods that can mix in shrimp or crab, and bivalves can naturally carry shrimp or crab alongside them. The chain also states that, for customers' safety, it does not remove ingredients from a dish on request.

この一覧は店内メニューのみを対象としており、テイクアウト・宅配メニューは別ページで案内されています。対象は特定原材料9品目(そば・落花生・小麦・卵・乳・えび・かに・くるみ・カシューナッツ)のみで、すかいらーくグループが一部ブランドで公開している推奨19品目(アーモンド・大豆など)は、ジョナサンのこの一覧には含まれていません。ドリンクバーおよびアルコール類は当サイトでアレルギー情報を公開しておらず、この一覧にも含まれていません(共有の注ぎ口を使用しているとの記載があります)。小鉢・ソース・ドレッシングなど選択制の商品や、しょうゆ・タバスコなどお好みで使う調味料も対象外です。調理器具・食器・揚げ油・パン粉や天ぷら粉などの衣・食材の保管場所は共有されており、そばを含む麺類は同じ調理器具・釜で調理され、各種ハンバーグは同一設備で製造されているため、表に記載のない品目でも混入する可能性があるとされています。また、一部の海産物はえび・かにが混ざる可能性のある漁法で採取されており、二枚貝にはえび・かにが共生していることがあるとされています。お客様の安全のため、食材を抜くなどの調理対応は行っていないとの案内もあります。

Allergy notes
Jonathan's allergen information is checked through a search tool shared across the Skylark group, filtered to this brand. It covers only the 9 mandatory items — buckwheat, peanut, wheat, egg, milk, shrimp, crab, walnut and cashew nut; the 19 recommended items the group discloses for some of its other brands (such as almond or soy) are not published for Jonathan's. It covers 369 dine-in dishes; takeout and delivery menus are listed on separate pages. Drink bar and alcoholic drinks are outside the scope of this allergen information. Items you choose yourself (small side dishes, sauces, dressings) and condiments used to taste (soy sauce, Tabasco) are not included either. Cooking equipment, dishware, frying oil, coatings and ingredient storage areas are shared; noodle dishes including soba are cooked with the same equipment and pot, and the various hamburger steaks are made using shared equipment, so an allergen not listed for a dish can still turn up. Some seafood is caught using methods that can mix in shrimp or crab. For customers' safety the chain does not remove ingredients from a dish on request, and because sensitivity to allergens varies from person to person, it recommends consulting a doctor and making the final decision yourself.
