I read somewhere that yakuza actually love open the bubble tea stall.
It's easy to make with cheap materials, don't need much space and manpower and make a really nice profit.
@lvxferre
"bubble" what?
The hell they're talking about after all?
But anyway remember, never compromise and use dry tapioca, always use wet tapioca.
And always makes "traditional" tapioca, just coconut and condensed milk.
