This street is Brittany Ln.

Suspicious of a couple of things here:
A typo (main stret)
and that i believe the name in parentheses (Newmarket Gazebo) should be tagged as an alt_name.

This building is marked as fire damaged ruins. It looks fine to me. We should check the history and/or the person who tagged it. I think they perhaps got confused with a building that burned down a block away on State Street, which appears to have been removed from the map at this point. For those familiar: I am referring to the building that burned down next to where Louie's bar (abandoned) is.

The Music Hall Lounge does take up all the area indicated, though only on the ground floor. However arguably it's the same building as addresses 123, 107, etc.

This is the ski lodge for "Whaleback Mountain" ski area.
