Like many reviewers before me, I also had to pick my jaw off the floor when I saw the SJCB logo in the PATH. Finally, a refuge for coffee lovers during the cold winter months of rushing around underground!
All their espresso-based drinks are great, and if you see a tall lithe man in a cap, it might just be Sam James himself serving you. If you're looking for something shorter than a latte, then ask Sam to make you a cortado (not on the menu) and enjoy it at the bar before returning to your hurried Blackberry existence.
It is cash only and on some days there is a small lineup despite two espresso machines. The hours are kept in line bankers (7am - 4pm) which is no good if you're working late. However, since the pastries are baked daily, and they never sell day-olds...show up just before closing and you might get a little treat. Don't tell them I told you.
