IETF-71: Philadelphia - 2008

A few of the IETF 71 attendees have recommended:

Spruce Street Espresso, 1101 Spruce Street (corner of 11th & Spruce Streets) 

Several attendees have rated this in the top 5 espresso bars they have been to in the U.S.  So if you love espresso, check this out.

One attendee wrote: This is a brand-new shop (their grand opening is on Saturday).  They use Counter Culture beans, Rio grinders, and a 3-group La Marzocco machine with a bottomless portafilter.  Very nice macchiato and espresso.  They are roughly 6 blocks from the hotel.
