Just found this thread as well and everybody's lists have brought back memories!
Those that I miss:
Le Lavandou - e60's
Il Menestrello - e50's
A la Fourchette - restaurant row west side
Il Nido - e50's
Il Bambino d'oro - e50's
Il Vagabondo - e50's - ok, not gourmet, but a fun change of pace
La Caravelle - w50's
"21" - w50's
Graybar Coffee Shop - Graybar building
Palm Too - e40's
There's more...but a good start!
