Pink Box, the self-described "Asian-European bakery" under construction in Squirrel Hill, will have its grand opening on July 7. It's located at 2107 Murray Ave. (map) in the old Chaya location that's been empty for years, it's across the street from a Korean bakery (Sumi's Cakery), up the hill from a Taiwanese bakery (Bubble Pi), and down the street from two others.
After checking it out while under construction I suspected it was by the same ownership of Ramen Bar (and Rose Tea Cafe), and that the above poster turned up on the Ramen Bar's Facebook page offers confirmation.
