on this rainy morning, i can think of nothing better than sitting at Grand Central Station’s Oyster Bar.  My my day trip to the United Nations brought me over to the Oyster Bar where i sat down at the counter under the glowing domed ceiling. The architecture is spectacular.  I attempt to read a book but instead stare at the raw bar in front of me.  I order a half dozen Prince Edwards and a bowl of New England Clam Chowder (the cream). Perfect.  Trust me, I toy with the Maine Lobster Roll but know I still need to walk.
