This tea house has a really chill, southeast Asia vibe with really amazing tea. I came in on a hot day and had some peach-mango iced tea, and it was really refreshing. They have a huge selection of teas as well as snacks. You can also enjoy a hookah with flavored tobacco if that's your thing. They also have free WiFi, which came in handy.
Since it's underground, I think this place suffers from a lack of business, and it's also a little pricey for tea. It's definitely a relaxing, comfortable atmosphere though and a cool place to go with friends.
