Cafe Eikokuya Tennoji MIO Ten is on the 10th floor of Tennoji MIO in Osaka and serves waffles, chiffon cake, and curry. Seasonal waffles come topped with orange and chocolate ice cream, and coffee can be refilled once for free. Around four groups were waiting after lunch, but seating took about 20 minutes, and the shop is quiet. There is no call bell or online ordering, so you have to call a staff member, which can mean a long wait for additional orders.
