Dragon Pizza has a different facade from Martsa, but from the overhead view, it looks like it is part of the same building.Not sure if the building where Dragon Pizza is located would also be part of it.
I wonder if they just intend to build on top somehow? If they are truly planning to do many future projects in the area, and want to maintain a good relationship with locals, including gov't (esp. after already upsetting some people in the Fenway area with their first proposal), it would seem really naive to just walk into a neighborhood and propose to blow away almost an entire block of their well-liked businesses. It's not like this is blight. From a business strategy point of view, it would seem like shooting themselves in the foot for future projects.
Sligo and McKinnon's are two of the last older establishments there, and to some degree the Burren too, although that was one of first places of the "new" Davis that rose in the 90's after the T station opened. I remember the Burren's opening shortly after moving there in the mid-90's, and then the Joshua Tree across the street not long after, and then it just steamrolled. Then the legendary, post-last-call Dolly's closed a few years later, which I lived near.
