Even the “regular” bowl differs
Yoshinoya’s regular gyudon is 633 kcal (protein 19.6 g, salt 2.5 g); Sukiya’s is 695 kcal; Matsuya’s gyumeshi is 687 kcal. Nakau’s signature is oyakodon instead — 655 kcal with a chain-leading 30 g of protein, thanks to chicken and egg.
Size matters far more than the chain
Sukiya’s ladder runs mini 464 → regular 695 → large 908 → mega 1,365 kcal — a 900 kcal spread within one menu item. Choosing the size, not the shop, decides your intake. On lighter days a mini bowl keeps gyudon around 500 kcal.
Salt stacks up through soup and pickles
A bowl alone is 2.4–3.0 g of salt; add miso soup and pickles and a set easily reaches 4–5 g. If salt matters to you, pick egg or salad as the side instead of soup.
