Please answer the following question: I know that the answer to the question "Who was the occupant at 300 George Street before some lab firms?" is in "A second biotechnology district is being planned for the median strip on Frontage Road, on land cleared for the never-built Route 34 extension. As of late 2009, a Pfizer drug-testing clinic, a medical laboratory building serving Yale – New Haven Hospital, and a mixed-use structure containing parking, housing and office space, have been constructed on this corridor. A former SNET telephone building at 300 George Street is being converted into lab space, and has been so far quite successful in attracting biotechnology and medical firms.". Can you tell me what it is?

SNET
