Situated in the heart of Petite France with its picture postcard half-timbered houses, this restaurant combines flavours from near and far. Its name suggests as much: umami is the fifth flavour in Japanese cuisine, alongside sweet, sour, bitter and salty. A keen globetrotter, chef René Fieger signs market-fresh cuisine scattered with exoticism, yet solidly rooted in tradition. The chef is entirely alone in the kitchen, conjuring up dishes that delight. Highlights include a slab of halibut, finely diced yellow and green courgettes, sliced green beans and an acidic, slightly creamy dashi-kefir dressing.
