Bubble Pi Baking Arts - A Japanese Bakery in Pittsburgh?
Yep, I was just as skeptical as you are. The place is awesome and, if you've ever been to Japan and experienced the cute little cafes they have you'd know how well she pulls off the charm and atmosphere.
I put a review up on my website, the link is here: http://wp.me/pVPwQ-2w
Definitely check it out and surprise yourself with some delicious baked goods. The owner is incredibly nice, too. She's at the bottom of Murray Avenue across from the Starbucks so it's a place everyone probably overlooks.
