The interior of San Seraph is small, compared to most in the city, but cozy. The walls are paneled in wood and red brick, with carved wooden molding accents. The brick edges are smoothed even, and the wood paneling is carved in intricate designs reminiscent of a Gothic cathedral. The entire building has a feel of being solid and old. The front has large paneled windows with the words 'San Seraph' stenciled in gold and blue. The walls are covered in framed pictures, awards and police memorabilia along with a section of remembrance for those lost in the line of duty. It is literally a wall of history of Prospect Law Enforcement. The wood panelling leads to the hard wood floor reflecting the same carving of the walls.
The left wall is lined with booths that are separated from each other by short walls, making them something like stalls, but giving a degree of privacy. Stereotypical Neon Beer signs, and a flat screen tv hang over the long bar. Wooden tables and chairs litter the floor. A pool table sits along the back wall covered in red felt, with a tiffany type hanging lamp illuminating the top, and leaving the rest in shadow. A collection of pool cues are on the wall beside it. The opposite wall holds a dart board.
The bar itself is on the right, and almost runs the length of the room. The bar counter is covered with a mosaic of blue and white stones under glass. The front continues the intricate carvings echoed elsewhere. Stools upholstered with soft comfortable black leather line the bar front. Behind the bar, several archways are carved into place over a grand mirror that reflects most of San Seraph and an extensive rack of bottles of liquor. Several taps for beer also line the back. A swinging door leads back to the kitchen.
At the very end of the bar is an open archway that leads to a second room where gatherings can be held without interrupting the main bar's regular business. To the side of the archway is a small table in the corner reserved for the owner. A large animal bed sits beside it.
