The big thing lately in Singapore, Tokyo, Malaysia is "brown sugar milk tea". I think it's hit NYC and LA but basically you take a tapoica milk tea but before you put the milk and tea in you coat the sides of the plastic cup with brown sugar syrup. Then, instead of the old tea + milk it's now like tea + cream and far more cream than tea such that it's more like sweetened tea flavored milk than milk flavored tea.
Search for "Tiger Sugar" for I guess the brand the started the new style?

There are apparently the equivilant of 20 teaspoons of sugar in 1 drink. Compare to 330ml of Coke which is about 7 teaspoons of sugar. The Malaysian government put out a warning as they got super popular.

I'm curious why now in Tokyo. Tapioca Milk Tea was popular in Taiwan in the 90s and made it Los Angeles in the late 90s early 2000s. People tried for years to bring it to Japan and I was told it was too sweet for Japanese tastes. But, now it's even sweeter and has some how exploded in popularity to a ridiculous level. It's like every spare store front has started selling.
