A Skylark-group family restaurant centred on the Tokyo area, a notch calmer than Gusto with a balanced Japanese-Western menu. Lighter options are relatively plentiful — useful for a reset day in a week of eating out.

Jonathan's publishes nutrition information for 318 menu items, and we list all of it here. It sits on the more substantial side of its genre.

At the extremes, “ちいさなしらすおろしごはん＆ゆで卵モーニング” is the lightest meal at 359 kcal, while “アンガスビーフ100％ステーキハンバーグダブルデミグラスソース” tops the menu at 1,281 kcal. The 922 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.
