Second location of Brew Tea Bar.
They make the best boba in Vegas in my opinion with a large selection of teas and an ever expanding menu. Absolutely true to their word on they'll remake it if you don't like it, the new location features a nicer interior with more places to sit and a larger area to wait for your drink.
If you really want to hang out, this location is a little less crowded for the most part, though they still get very busy. I don't know how long that'll last though.
