Simply put: my favorite working place in Squirrel Hill. The tea selection is huge and the very friendly staff will be delighted to offer you advice or some to smell if you need guidance or odors to help with your decision. There is a nice selection of biscotti, donuts and various other hot-drink complements. Oh and if tea isn't your thing, try the six amazing hot chocolate flavors (raspberry is incredible) or there's also decent coffee.
The ambience and decor are bright and friendly and you will never run out of outlets. I once calculated that there are 3-4 per person when it's full (seriously!). So, if you run out of outlets you are carrying way too many devices with you.
If you end up hungry for something more substantial than the sweet snacks, they also offer grilled cheese sandwiches for $5, which will give you that extra boost when you need something more savory.
This place really can't be beat.
