I kind of love this chain, and all the locations aren't super close to me, but I do start to crave their bubble tea. It's got a decent menu but limited in options, but the ability to customize makes it special (or the fact that they call it out is - you can probably do that with any bubble tea establishment).
There is always a line up, but it gives me time to think about what I want to order! I've been in love with the QQ Jelly (mix of lychee jelly and pearls) in both the grapefruit and passionfruit flavours. The roasted milk tea is also quite tasty - how have I not gotten a stamp card yet?!
It's a bit loud if you want to hang out there, and the seating is limited but they do a good job trying to maximize sitting space.
