Where was this place last year?! I used to live close by, and I would've easily been a regular at this adorable, bright coffeehouse. The baristas are friendly and happy to explain the offerings - which unfortunately can't be said about all Pittsburgh cafes. Even though Adda's awfully new, you can tell they have a solid regular crowd, which speaks to the great coffee, customer service, and location. It's a tiny shop, but very quiet so it's great for getting some work done. My latte and biscotti were fantastic! I'll definitely be back here often
