IRUCA Tokyo in Roppongi is a cozy ramen spot that's all about that umami goodness. The owner-chef has crafted a unique soup by blending chicken, pork, shrimp, and shellfish dashi for layers of flavor. Their 'Porcini Soy-sauce Ramen' with porcini mushrooms and black truffles is a fragrant delight, while the 'Salted Yuzu Ramen' adds a modern twist with ginger and spices. It's a small shop with big flavors, perfect for a satisfying bowl of noodles in Tokyo.
