When you talk about the gastronomy of MADRID, I remember a video by LUISITO COMUNICA, a well-known influencer, who visits a restaurant and says that the best food in MADRID is COCIDO MADRILEÑO. Many influencers today focus on trying the food of the countries, giving a guideline for those who are going to travel. I think it's good because you have a reference of what to eat and restaurants to visit.
I wish you a happy start to the week.
