I still think about the blood sausage with egg and the tempura potatoes that are so crunchy and delicious. Regarding desserts, I totally advise against Portuguese serradura: it is whipped cream with condensed milk and is very cloying. If possible to share several and let one spoonful per head if several are excited. The Manchego cheese cake seems like a better option to me (warning ⚠, it tastes a lot like cheese, there are people who don't like that). There are gluten-free options.
