It's a great place to not only stop by when you're shopping on Walnut St. It's also a great place to study or get some work done. Their coffees are always legit and they will get your order made quickly.
There's a small study room in the back, leather couches are available, and small tables everywhere. In the summer they will open the glass wall/windows so you can feel the breeze and make you feel like you're sipping on your coffee outdoors.
One downside about this place is, the restroom is so dirty and smelly. Maybe it's because they have too many customers but I really wish the staff would get the cleaning done right. Bad restrooms give customrers a bad impression!
