Crazy Mocha is Pittsburgh's yinzer Starbucks alternative.
The coffee is solid, the pastries and baked goods are usually a day old, and the interior is utilitarian at best.
That said, the staff is friendly and knowledgeable - which makes it a great coffee pickup spot. The free wifi is a great plus for when I have to work at the shop for an hour or two, but it doesn't give off the vibe that I should ever make myself too comfortable.
