I visited aca, the pinnacle of Spanish cuisine located in Nihonbashi.It is the best Spanish restaurant in Japan and ranks second overall on Tabelog, truly representing the Japanese restaurant scene.Despite its accolades, the atmosphere in the restaurant is never intimidating; it feels warm and welcoming. This is undoubtedly due to Chef Higashi's gentle personality.His overwhelming curiosity and skill in cooking naturally blend with a genuine care for each guest. Dining at aca is not just about delicious food; it’s an experience that nourishes the soul.The course I had that day was exceptional.It started with a snap pea caldo, followed by a bocadillo, grilled swordfish with herb salad, and fried sweetfish. Each dish beautifully contrasted in aroma, cooking technique, and texture, showcasing both the strength and delicacy of Spanish cuisine.The ajillo featured a luxurious combination of shark fin and shrimp. The layers of umami were remarkable, making it a memorable dish.The jamón serrano soup had a deep flavor that seeped into the body. The grilled Kobe beef tenderloin was perfectly cooked, infused with the aroma of the wood, bringing out the essence of the ingredients to the fullest.And to finish off, the paella. First, the exquisite hairy crab paella, where the crab's umami permeated each grain of rice, achieving perfection in aroma, flavor, and aftertaste.Moreover, Chef Higashi's thoughtfulness shone through when he prepared a squid paella just because I hadn’t tried it. This kindness reminded me why aca is such a special place.For dessert, we enjoyed melon, ice cream, Catalana, and Spanish chocolate. The satisfaction lasted until the very end.The quality of the dishes, the warmth of the people, and the comfort of the space—all come together to create a unique Spanish dining experience that Nihonbashi can be proud of.Thank you, aca, for another truly amazing experience.
