At /M (called 'Barra M'), the chef at Tiradito & Pisco Bar, Omar Malpartida, directs from a distance and thanks to a well-trained team and top-notch products this space that's more informal than Tiradito. Malpartida compacts his creativity and Peruvian roots (and derivatives) into a palatable sampling of tapas and light meals that everyone up for exotic flavours and fusion cuisine will enjoy. You might find a couple of types of ceviche and even Asian gyozas and baos but also other more traditional options such as braised chicken and osobuco stew, which are meant to be shared dishes.
In Chueca, restaurants are open late, in some areas you'll find a mix of tapas, tacos and burgers, and in some places you can't even get a table unless you book in advance. The decor is just as important as the cusine, and there's such a wide variety to choose from, you won't have trouble finding something you love. It's the perfect area in Madrid to go out for dinner and have drinks afterwards. A bit of advice: the farther you go from Plaza de Chueca, the more affordable your bill will be at the end of the meal.
