Yes it is tricky to find the entrance to this place, as there is only one way in and one way out. Nonetheless, the place was nicely decorated for a new establishment and the staff was kind. Maybe it's more of a 3.5 stars, but since I had a decent experience, I will round up to 4 stars.
I tried one of the new "bubble tea" drinks in raspberry green tea. However, it was jelly instead of standard tapioca bubbles and the drink was watery milky so it wasn't quite what I was expecting. Regardless, the cup design was cute and the atmosphere of the place makes for a nice hangout place to study or work or chat with friends.
