Elaine’s, a venerable restaurant on New York City’s upper East Side, is closing in nine days after being open for 48 years. Elaine’s, in its heyday, was a hotspot place to be seen. Woody Allen played his clarinet there. Authors celebrated their books there. Celebrities went there to be seen. Elaine Kaufman — the “Elaine” in Elaine’s — died six months ago and now her namesake restaurant is following her to the grave.
