El Señor Martín is a steakhouse in Madrid, Spain, and the useful context is what kind of evening it seems built to deliver. The draw is the quality of the grill, the meat program and the wine or cocktail support around it; at a polished mid-to-high price point, it should be judged as a polished dinner worth planning ahead for. Michelin selection gives it a credible place in the dining conversation, even without the expectation or formality of a starred meal.
