Top 5 places to visit in Philadelphia.

[Corduroy]

If you're into writing; the Edgar Allen Poe house. And avoid South Street at certain times of night. Olde City has some great nightlife, but is crazy expensive.

[AtomicPunk]

Monk's. Just sayin.

[lebshiff21]

South St. has become somewhat of a disaster over the past several years. I would say:

Italian Market
Reading Terminal Market
Eastern State Penitentiary
Get a cheesesteak, doesn't really matter where. I like Tony Luke's.
Independence Hall/Washington Park area is great.

Mutter Museum is interesting

[RippinLt]

broad and market after the phillies clinch any title

[Paulsan]

Eulogy's is a good place to start.

[MontcoPA]

The Stoogeum (in Lower Gwynedd Township)... although its only open about once a month. The Trolley Car Diner. A Phillies game. Olde City. Any one of the vast number of museums in and around the city.

Philadelphia is hugely diverse, and you can have a top 5 tailored to anyone's interests.
