If you are in a hurry and want a coffee or snack on the run, don't go to the Starbucks on 48th Street and Park Avenue in mid-town Manhattan. The queues of caffeine-deprived besuited bankers and lawyers are huge.

A simple filter coffee can take 10 minutes. Opt for a tall skinny latte with a shot of vanilla and a cherry on top, and you could be forced to cancel your meetings for the rest of the day. But you can always use your Palm, mobile phone or BlackBerry to let the office know that you are not coming back until you've had your fix.
