KOI bubble Tea ~ yet again

Left: Cacao Barry with pearls
Right: Grass Jelly Milk Tea

Have you tried it yet?

We dropped by TPY Koi after dinner today.

For a change, we tried the cacoa barry instead of 2 grass jelly milk tea

I like the TPY branch as the queue is always reasonable and
the milk tea taste good.

And the Cacao Barry is really nice
if you are a strong chocolate lover!

I seriously wonder, what is the amazing draw of KOI???

The queue @ their AMK branch is always "amazing"!
No matter when, the queue is never ending.
What is so great about KOI?
Is it a craze or is it the drink?
