The diner's exterior and interior are both very damaged. In the north corner of the diner, a Chryslus Cherry Bomb can be found smashed into the building. The interior consists of a counter and a kitchen. There is also an outdoor seating area.
- Taking Independence: Preston Garvey and the other Commonwealth Minutemen use this location as a staging ground for their efforts to retake the Castle.

Behind the scenes
- The full name of the diner is "Sullivan's" but this cannot be seen in-game since one can only read "ivan's" on the sign. It is based on the Sullivan's diner, located at the same spot near Fort Independence. Founded in 1951, it's considered a South Boston landmark.
Sullivan's appears only in Fallout 4.
