Day of the Outlaw (1959)

Cf., additionally:
Lunch date at Café Kitsch in Spontaneous Combustion (1990)
Sarah and Khalid encounter inside elevator in Djinn (2013) (I contend as solid, well-constructed a scene as in any Oscar-baity, sophisticated fare you can think of last year.)

Frames as triangulations, precise shot/reverse shots, evolving frames (not just around tables.)
