What is the importance of the Chestnut Tree Caf© (Part 3)?

Earlier in the
novelwas at the cafe and he saw
three men (Jones, Aaronson, and Rutherford) who he knew had been
erased for
their disloyalty to the Party. He knew because he helped to erase them from a
news
article that came across his desk. He was uncertain if his memory was
correct, but he was fairly
certain that these were the men. They were
important Inner Party members who had been in league
(supposedly) with
Goldstein. After his experience in Room 101 Winston spends his days in the

Chestnut Tree Cafe doing just what those three men had been doing, drinking Victory Gin
and
playing chess. In part 3 chapter 6 Winston is aware of having known them,
but never allows the
memory to fully emerge for fear of what might happen. He
does in a sense realize, however, that
this where people like him went,
people who had been reconditioned and forgotten, or perhaps
even
erased.
