It's a great experience for people visiting Shinjuku to explore the hidden alleys and various bars and izakaya. Kota, my guide, is an incredible guy and will tell you about the nooks and corners of Shinjuku. Experience: you'll get to try different types of izakaya food, and then comes the best part, the sake. There is a full-fledged sake tasting experience, and I can assure you that by the end of the trip, you'll make friends with everyone.
