A pub located right next to Boston Commons.
The pub is divided into two halves, the main room with the primary counter and the rear pool room, with the single bathroom in the connecting corridor. The manager's office is adjacent to the main room.
- 2 baseball grenades on the manager's desk.
Behind the scenes
The entire layout of the bar is a homage to the television show Cheers (which was set in Boston), right down to the skeletons at the bar. The entire cast is represented, the skeletons of Sam Malone, Diane Chambers, Carla Tortelli and behind the bar. At the stools, in their appropriate corner are the skeletons of Norm Peterson and Cliff Clavin wearing his Postman uniform.
Prost Bar appears only in Fallout 4.
