Huge enclosed market in the heart of Philly with about every kind of food that you could ever want. Definitely check out the groceries, which are definitely worth the walk, especially if you live in the city.
One of the cooler bar scenes in Philadelphia. The Ritz was formed inside an old bank, and sitting inside, you can definitely tell. It's a very large open bar room with dome ceilings and plenty of drinks/dinner seating.
Drinks, as you might suspect, were pricey, but were very tasty. I'd recommend going here at least once when you're in Philly. It's a block from City Hall.
