Brew Tea Bar is one of my favorite places to get bubble tea in Vegas. The flavor is exceptional and they usually come out with it lightning quick. They also care if you are satisfied with their product, and are willing to change anything that you are unsatisfied with.
The space however, is really small. The decor is cute, but there are only a couple of seats available to sit at and not that many tables either.
In my experience, the bathroom was pretty clean when I used it. Plenty of parking spots available too, but it can get crowded and you may have to park far. Get some steps in!
