Price checked 2026-10-04; Burger King Spain publishes no prices on burgerking.es or in the menu data behind it: prices appear only after you choose a restaurant in the ordering flow and vary by restaurant, so every item here reads in-store pricing. The few euro figures quoted in blurbs are promotional prices printed in the site's own promo copy or legal pages (Happy Hour, Family Day, app pick-up offers, delivery deals) and apply only under those conditions. Calorie figures are for the single burger or the portion named, taken from the site's own nutrition table, a PDF dated August 25, 2026, which predates the Full Flame, Pulled Pork and Cheddar Bombs.
