One July weekend, I had the opportunity to combine two of my favorite activities -- riding my bike through Manhattan and visiting new coffee shops. My family was traveling elsewhere, and New York had not yet fallen into the drippy hot torpor that has marked recent days. I rode down the west side a bit, diverted to to the Hudson River trail, then passed through TriBeCa, Chinatown, SoHo and my old East Village stomping grounds before chugging up the East Side -- a loop of sorts.
