The washrooms are decent, sometimes lacking soap but it's pretty good. There's wifi so that's always a bonus.
The service is pretty fast and the bubble tea is one of the best. All my friends love this place to death and if I wasn't deathly afraid of high sugar things, I'd probably live in here. I've only ordered around 4 times and sometimes when I ask for less sugar I still taste a lot of sugar. When you get your drink customized you might not get it exactly the way you'd like it.
The atmosphere is great for socializing or just doing work if you're able to work with the small conversations going on around you.
