Our favourite travel agent in Asia, Sébastien Duval, discovered in June/July 2015 the Panda Café in Tokyo’s Taito ward while exploring Asakusa area on foot. He strongly recommended us this great coffee shop (and restaurant) near Tawaramachi subway station notably for its small terrace, delicious desserts shaped like animals, and exciting room for children upstairs!
