A holy marriage of Japanese and French culinary traditions resides in blissful splendor at Nob Hill’s Keiko. Tucked inside an unassuming art deco apartment building, sumptuous draperies and chandeliers, antique-inspired seating and intricately designed tablewares evoke a kind of vintage luxury in Keiko’s lounge, bar and salon. Chef Keiko Takahashi’s tasting menu ($165) is a brilliant progression of flavors from Europe and Asia with dishes like foie gras “espresso” appearing side-by-side with Japanese scampi and fresh fish from the Tsukiji Market in Tokyo. Three separate wine pairings—from the entry-level “Grand” pairing ($148/person) to the exquisite “Kyukyoku” pairing ($850/person)—enhance each inspired course.
