National Cheesecake Day is Saturday, July 30th. Celebrate by having a piece of cheesecake in NYC. Where? The world’s most famous — and arguably the world’s best cheesecake is at Junior’s, which has baked and sold millions of them since opening in 1950. The original Junior’s location is at 386 Fulton Street in Downtown Brooklyn, with additional locations in the lower level food court at Grand Central Station, on West 45th Street between Broadway aand Eighth Avenue in the Theater District, and at MGM Foxwoods in Connecticut.
