Anthony's has got to be the greatest, throw-back coffee house that I've ever seen. Ferrara's in New York is beautiful and great but Anthony's in South Philly is where me and my crew have our meetings over a coffee and cannolis.
At Ferrara's, you have a waitress bring you your coffee and cannoli but who needs that? In South Philly, you go get a bunch of cannolis from Isgro's on Christian St. (2 blocks away) and chow down on them over a coffee at Anthony's, which has great coffee and cappuccino. In the summer time, sit outside and watch the Italian Market shoppers do their thing.
Anthony's is excellent and the people there are outstanding.
Pros: inexpensive, charming, great people
