Yes Boba tea, or tea with tapioca pearls, is everywhere. Yes, they are all delicious. This is just one of them but I highly recommend it. It sits in the underground part of the train station exit on George St. and Bathurst St. and is connected to an Asian grocery store. They have soy milk or regular milk, you can get with or without pearls and an array of flavors. It is the perfect refreshment for a typical hot sunny day. If you think you don't like tea then I dare you to give it a try. It's slightly sweet to most people tend to like this type of tea even when they don't like typical hot teas.
*Side note: They also make the BEST Nutella crepes. They are grilled to perfection and have a slight crispness to them that others don't manage.
