A hamburg-and-steak family restaurant strongest in Hyogo. The official nutrition/allergy PDF lists calories and salt per item, including sauces and toppings; protein and fat are not published.

Tomato & Onion publishes nutrition information for 183 menu items, and we list all of it here. It sits on the more substantial side of its genre.

The lightest meal is ““牛肉100％！！”弾丸ハンバーグ【ハーフ】” at 348 kcal and the heaviest is “”鉄板”うな玉ライス（特上＆大盛り）～ひつまぶし仕立て～” at 1,825 kcal. The 1,477 kcal spread means your choice matters a great deal here.

Plan on adjusting portions if you want to keep the meal light.

Some single items carry over half the Japanese daily salt target (7.5 g for adult men). Leaving the soup or skipping table condiments is the easiest way to bring that down.

The official disclosure is essentially calories only; protein and other breakdowns are not published, so we list only what is disclosed.
