Bagel shop 5 minutes walk from Akihabara train station. Only opened from 11:00 to 14:00 on weekdays and the 1st and the 3rd Saturdays of the month. Haven’t had a chance to try their bagel sandwiches but the bagels are delicious enough to eat on their own. It is a branch of Garden Berries in Chiba which I have visited before.
