Carefully Selected, Large Hiroshima Oysters
Big Boy’s oyster fry uses large oysters carefully selected from among Hiroshima-grown oysters. The coating is crispy and the oyster inside is plump and juicy. With each bite, a gentle aroma of the sea rises to the nose. The rich, savory flavor of the oyster deepens the more you chew.
Two Sauces Served on the Side: Tartar and Rich Sauce
The sauces come on the side, with two options: tartar sauce and a rich sauce. Each offers a different flavor, so you can dip according to your taste or alternate between them to compare.
Available à la Carte
The oyster fry can also be ordered à la carte (2 pieces). Add it to any dish you like to create your own combination, or enjoy it as a snack with drinks.
