Of all the places in Pittsburgh where I have tried bubble tea, Rose Tea Cafe definitely has the most extensive selection. They also seem to have the most authentic setup, complete with a bubble tea shaker machine.
I had the black tea milk tea. It wasn't overly sweet, but it had a bit of a chalky texture from the mix they use. Their boba are okay, I like them to be somewhat sweeter, these were on the bland side. I did like the smaller size of their boba, some places use large ones that easily get stuck in the straw. All in all I liked the flavor of it overall, other than the chalkiness that is left behind in the cup. I am eager to try some of the other flavors.
The service was fine and we got our drinks quickly. We have not yet tried the food, but it definitely smelled good in there, so we'll give it a go next time.
