There was a brew pub in the building on the South side of the mill pond for a few years that I used to go to quite a bit, and when my son was a toddler and we were looking for a daycare place, there was one in the basement of one of the Mill buildings. But it felt weird and closed in so we opted for somewhere else. The closest I get these days is the Indian restaurant across the street.
Yes it’s been a startup office space for the last quarter century. I did a few startups in various spaces there. And Monster was HQd there in their heyday as well. There were many artifacts of DEC still around the campus.
