Napoleon Slice calories and nutrition

Porto's doesn't publish calories or nutrition facts for its menu, including the Napoleon Slice.

Ingredients and allergens

Porto's describes the Napoleon Slice as made with:

  • Puff pastry made with European-style butter

We can't confirm anything beyond that. Porto's kitchens handle nuts, dairy, wheat and meat, so tell the counter about any allergy before you order.
