Autumn Dessert: Big Boy Adds Chestnut Mont Blanc Fudge Sundae From October 20

Big Boy and Victoria Station have added an autumn dessert to their menus in Japan: the Chestnut Mont Blanc Fudge Sundae, featuring freshly piped sweet chestnut paste.

The sundae goes on sale at participating Big Boy and Victoria Station restaurants from October 20, 2026. No end date or price is specified in the release, so guests should check with their preferred location for current availability.

The dessert is served with a gently warmed brownie, marron ice cream with chestnut skin, sweet chestnut paste, syrup-preserved chestnuts, caramel sauce and crisp crumble. It is available in restaurants rather than through a separate pop-up or online sales channel.

Pieces of chestnut in the ice cream add a pleasant bite.
