Come to Lisbon

It turns out that Portugal is a socialist country in Europe, having not experienced World War I or World War II, and has lived by plunder, making neighboring countries "lemon essence."
The egg tart originated in Portugal and was made by nuns in the convent using egg yolks, while the leftover egg whites were used to starch the nun's habits.
Interesting event that happened today: I waited in line for a long time to get to the century-old Pastéis de Belém shop, saw a ton of desserts, and thought since I’m here, I might as well ask the staff twice: Besides the egg tarts, what else do you recommend?
The staff kept refusing: "No," pointing at the egg tart and saying: only this😅
