2) See what life was like for early American settlers in Philadelphia | Make sure to walk around Elfreth's Alley in Philadelphia, America's oldest continuously inhabited residential street. Take a cup of flavoured coffee at ICI Macarons & Cafe; admire the gorgeous preserved homes and walk the cobblestone streets to see what life was like for early American settlers. |
3) Remember about BYOB (bring your own bottle) in the restaurants in Philadelphia | Philadelphia (as Pennsylvania itself) has some strange liquor laws. Spirits are extremely expensive at local restaurants. Many establishments let you visitors bring their own alcohol, so feel free to ask if it is possible. |
