Bubble Tea trend

Today's picture: Tea drink from Gong cha

When I was in high school the 'bubble tea' shops were becoming popular and shops were opening all over the place.
The first place was Easyway. Afterwards Chatime, Gong cha and share tea has come along. Now that the drink is accessible anywhere it's no longer special. 
I was never a fan of the pearl inside the drink. I would get grass jelly or coconut jelly instead.

A few years ago a similar trend happened with the self yogurt shops. Yogurberry shops started opening. 

Wonder what the next food trend will be?
