The only bubble tea in the west end where I can sit and work until a reasonable late hour. For the most part, Cup O House doesn't get that busy which is nice and it's open late compare to other cafes in on this side of town (11pm weekdays, 12am weekends). It's a bit pricey, the flavour isn't bad (I prefer Chatime or Coco) but on a positive note, if you're staying a while, their jumbo size is the perfect size! Their drinks are quite sweet, so if you're not a fan of sweet drinks make sure you adjust the sugar level. Lastly, get a stamp card if you think you'll come back multiple times. My go-to is simply the milk tea with bubbles.
