Sharetea has decent bubble tea but you can find tons of better bubble tea stores in GTA and Toronto. I prefer their bubble tea over many bubble tea franchises in Toronto due to their consistency.
They have a great selection of beverages, fruity ones, chocolate ones, and caffeinated ones. This location is very close to downtown core, probably 10 minute walk away from Dundas station. The times that I have been here, the store has been empty. They make their drinks quite quickly, and the quality is probably around the same as any other sharetea you go to.
