I wrote an article a while ago about Fado Restaurants in Lisbon: https://lisbonguide.org/fado-restaurants-in-lisbon/
Fado is the traditional music of Portugal, that locals sing for a long time.
Additionally to the places mentioned in the article, I would like to highlight the following place in Lisbon for Fado Show, without having to eat (without meal).
The show takes approx 50min in Chiado, and costs 22EUR per person.
You can see more details and book online here: https://fadoinchiado.com/
They have one show per day at 7AM, from Monday to Saturday.
