A well-known Jamaica Plain builder who hopes to open a casual seafood restaurant next to Green Street T failed to get support from a bellwether neighborhood committee for the liquor license he'll need. Chris DeSisto of Maple Hurst Builders will have to decide whether to take his request to the city's Licensing Board without a green light from the Public Service Committee of the JP Neighborhood Council. The board stalemated 4-4 Tuesday during a packed community meeting at the JP Police Station. DeSisto aims to anchor a new multi-use building at the corner of Green and Amory with a restaurant. "Bartlett Square 2" would mirror many aspects of his existing Bartlett Square building across the street.
