Tea Time is awesome if you like little hole-in-the-wall boba spots (aren't they all?) with a very clean & open atmosphere. Their boba teas are delicious & they also have an appetizer/snack menu if you're looking for something a little more solid.
I love their egg pudding topping & they have quite a few others if you're feeling adventurous.
Heard they can get really busy on weekday mornings with local traffic but the days I've gone (late noon) they haven't been busy at all. And their tables and seats are pretty fun to sit at too (high tables & seats against the wall). There are electric sockets if you plan on staying a little longer to study & plug in your laptop. Place looks new with its decor & paint even though it's been open for years.
They're getting more traffic now & they deserve more recognition. And it's pretty hard to find good boba spots in the North West/Centennial Hills side of Vegas when you're a local.
