What’s the most important room in the house?

You might answer the kitchen, as that’s where the food is; or the living room, as that’s where the TV is; or, of course, the bathroom for obvious reasons. But the play “The Dining Room,” a comedy by A. R. Gurney, makes a case for this often-overlooked (if you even have it) space that was a stoic witness to change for middle-class America through the 20^th century.

In the Belfry Theatre production, occupying the Switch Theatre in Fishers through Jan. 30, seven actors show us 18 scenes through 40 years (1939-79) with one nice but not quite antique table and set of chairs. Though it finally goes on the market in the era of Disco, this house is mostly home to members of a single family. They wouldn’t consider themselves wealthy but are well-off enough to have at least a cook and maid, at least in the early decades.

The fourth wall (French doors, we are told) becomes our window into their lives, as even in the stuffy past, there are youngsters looking towards the new while elders cling to the best of what has been. As the scenes bounce back and forth through the years, parents become grandparents, children become parents, and there’s always something we really shouldn’t talk about at the table.

The ensemble of Mia Gordon, Jennifer J. Kaufmann, Tim Long, Jeff Maess, Tom Riddle, Addie Taylor, and Debbie Underwood splendidly take on what must be a fun acting exercise, inhabiting the various ages and characters – only one is an actual youth, so “child” roles take on extra charm as the older hands truly commit. Under the direction of Diane W. Wilson, the scenes flow easily into each other, sometimes having a person or two from one era sharing the space with oncoming folks from another, making the room, in a way, timeless.

Though real tensions and drama sometimes pop up, this play is mainly a gentle comedy, the kind of feel-good family portrait that we can use about now. Even if we aren’t mid-century WASPs, we can feel a sting of familiarity in dealing with relatives in changing times. And it’s good to find something to laugh about, or at least knowingly smile, in it all.
