Ô Bubble is a cafe near Sacré-Cœur that serves bubble tea alongside bagels and cakes. It offers many types of taro milk tea and fruit bubble tea, with carrot cake and bagels on the side. When ordering, you can choose pearls such as tapioca or aloe balls, and there is seating in a garden at the back of the shop. The restroom is in the basement, but it is small and its upkeep is lacking.
