My local b+m is Barclay Rex on 42nd street in Manhattan. Their pipe tobacco stockist, Terrance, is very personable and happy to answer questions and offer insight. He's given me a few samples of different flakes to try and each one has been right up my alley. Plus, they stock Penzance, Stonehaven, and other Esoterica blends in bulk. I actually prefer this store to the venerable Nat Sherman just down the street as Barclay Rex has a more down to earth, approachable vibe. If in town, be sure to pay both locations a visit to see for yourself.
