Bubble Tea

I'm crazy about it and rarely come across it where I live. If I want some I have to go an hour from my place to the Chinese district but tonight while shopping with my daughter at a mall that I rarely go o (not close to my house either ) I came across a place that sells some !!!
WOO HOO … Without hesitation I purchased one (old habits of drinking anything and everything are not totally home … )
I turned out to be an 12 oz but now I have NO idea how to log it as there was no nutritional value available.
It was coconut made with milk including the tapioca pearls and it was a 12 oz.
I did a little research on the net and it seems to be around 250 cal… Would that be accurate ?

Thanks for helping
