Latenight...cozy and elegant and/or cozy and atmospheric...have considered but have doubts about:
-- Molyvos (mediocre comments here)
-- La Luncheonette (a favorite of mine but they don't stay open very late)
-- Queen of Sheba (atmospheric and fun but eating with one's hands maybe not be the best idea in nice opera clothing?)
-- Cafe Des Artistes (meeting up in their parlor room beforehand so going back would be redundant, and the food is only average anyway)
Suggestions and rebuttals kindly requested...
