My friend works in this area and she's visited Plentea plenty of times. Instead of eating lunch like normal people at noon, she took me to Plentea and greeted the extremely friendly staff, who loves teas and Sailor Moon.
Such a great atmosphere!!! And they make your tea to perfection. AND FAST. They're so fast! I didn't even finish studying their menu (I was busy picking out the tea for my next visit).
There is a beautiful upstairs for peaceful studying or (in my case) lots of beautiful catch-up gossip. In our most polite voices, of course.
Try try try try, and try ALL of their teas. They are as delicious as they sound. But Plentea isn't just a tea + hot water, they make really good tea lattes. I'm a huge huge huge fan of rich teas with rich milk, who knew they go so well together!!!
