I haven't tried many combinations. Probably 3 at the very most.
I wouldn't say it's my favourite as I don't think I've tried enough combinations but I really, really like Apple Fruit Tea with Mango Boba (from Bubbleology). I've been craving it for a few days now but it's a 20-minute bus ride away.
I'm fairly new to Bubble Tea so for now it's a treat every few months. I'd be interested in trying a milk tea with the Tapioca boba next time I have Bubble Tea.
Never tried it, it's probably chock full of mercury and radioactive material from North Korea, also not sure why anyone would by a prepackaged drink from bubbleology, they should make it in front of me so I can watch them.
