Starbucks at Shirokane-Takanawa is often very crowded on weekends. Visitors literally occupy tables, so if you want to have a cup of coffee and talk, why not go down to Cafe Esperance?
The cappuccino here is well-priced at around 300 yen. With the arrival of autumn, the interior of the cafe is decorated for Halloween. There is almost always a free seat available here, and cappuccino or latte don't consist of 90% milk.
