I have 4 words to complete this review: THEY DON'T USE POWDER.
That's basically it, the regular boba is plump and squishy and sweet, and for the love of all that is good in the world they do not use powder for their tea. It is excellent, amazing, I would go so far as to say it's perfect.
The prices are pretty reasonable $3-4 bucks for small/large and depending on if you add boba and such.
I remember the only place I ever found with good boba milk tea previously was at Tea Station and even though they are very very good... they charge up to $7 dollars for a drink.
TeaStreet is the cheaper version of Tea Station, but without sacrificing quality (it's as good or better than Tea Station).
Coming from Southern California... this place is very very very legitimate.
