If you don't know what Tapioca is, I'm sorry to say but you should get to know it!
Tapioca Express is an excellent store that sells a variety of drinks and even food! Snow bubbles, normal tapioca drinks, ice teas, teas, coffee, chicken, bento boxes, jelly drinks, &etc. are all sold there. The price may be a bit on the expensive side but they're delicious and fast at getting your order done!
The atmosphere in this Tapioca Express store is wonderful. It's a great place to hang out with your friends and chat. The entire store is filled with tables and chairs, it evens includes sofas! There is a foosball table, video games, a TV, and wireless internet. So basically you could spend a Friday afternoon there just making idle chat with whoever.
