I most recently visited Adda when I was looking for a quiet spot to study for a final, while enjoying a hot drink. Adda was the perfect spot. Although it's not super quiet (no coffee shops are), I was able to find a table easily (hard to come across in Shadyside during finals week) and was super cozy while I got work done & enjoyed my tea. They have tons of tea flavors and lots of great coffee drinks. They also have juice from Pittsburgh Juice Co., chocolate, pastries, and lots of other goodies. I chose the chocolate cinnamon Rishi tea- wow, was it amazing. I loved that they served it in a little mug with a timer, so that I knew when my tea was perfectly steeped. I will definitely be returning!
