Pearl Lady is a tea shop selling tapioca drinks, located outside the ticket gates inside the Ikebukuro Station building. It adds black sugar tapioca and white rice cakes to matcha milk, white peach tea, and jasmine milk tea, and lets you adjust sweetness and ice levels. Lines form depending on the time of day, and even when the evening queue is long, drinks come out quickly. A line of 10 people takes about 20 minutes.
