Sua is the height of softly lit sophistication and cooking that provides a new slant on nouvelle cuisine. Dishes are organised around four temperatures – 25°C, 50°C, 75°C and -2°C (desserts) – and it draws its inspiration from the Basque Country, Spain’s hothouse for culinary innovation. The service is faultless and adept at helping you negotiate your way through the menu, but we suggest the €36 menú de degustación (tasting menu) , which gradually increases the temperature.
