The Local Way to Say It
For Madrileños, asking “What do you think?” is all about getting a genuine reaction to a new idea or plan. When chatting with friends over a caña in La Latina, you’d naturally use ¿Qué piensas? (What do you think?). It’s direct, friendly, and invites a personal reflection. For a more formal situation, perhaps discussing business or with someone you’ve just met, you’d opt for ¿Qué opina usted? (What is your opinion?). This shows respect and politeness, common in Madrid’s social fabric.For example, if you’re trying to decide where to eat in Malasaña, you might ask, “Tenemos que elegir un sitio para cenar, ¿qué piensas?” (We need to choose a place for dinner, what do you think?). Or, after explaining a new project to a colleague, “Sobre la propuesta que te presenté, ¿qué opina usted?” (Regarding the proposal I presented, what do you think?).

¿Qué opinas? (What’s your opinion?) – Less common for general
