When Philadelphia was settled by Europeans, the core of the city was on the eastern part of the city, nearby the Delaware River, in what is now Old City. City founder William Penn plotted out the entire grid street structure of Center City from the Delaware to the Schuylkill Rivers so that the city would develop in an organized fashion, and over time the city did extend development westward and beyond.

Because Old City was where the business and market areas were concentrated, much of the western half of Center City became the residential neighborhood. A lot of the housing stock dates from the 1800s, when wealthy businessmen built their homes alongside communities of working-class neighborhoods. In the 1950s, Philadelphia began to expand the business district westward as well, and with the University of Pennsylvania located just across the Schuylkill River, the area has retained its desirability for many residents. In particular, Rittenhouse Square is surrounded by high-rise apartment towers housing the moneyed elite, and the neighboring blocks have long been one of the most desirable residential locations in Philadelphia. Fortunately, the park itself has retained a unique ability to exclude no one, no small feat considering Philadelphia's history of tension between different racial and social classes. On any given day, especially weekends and in the summer, the park will be populated and used by just about anyone and everyone.

Commercial businesses came westward with the planning of Penn Center, a rather unwelcoming business district west of City Hall just north of Market Street. However, this enabled other commercial development to occur in the area, and in 1985 One Liberty Place became the first building to break the unofficial height limit in Philadelphia, which was top of Penn's hat on City Hall. With a ground floor mall at the base of the building, this development helped spur retail development, which in turn contributed to the reversal of urban blight and flight in the early 1990s. Today, the three blocks north of Rittenhouse Square (Walnut, Sansom and Chestnut Streets) and eastward to Broad Street is Center City's upscale shopping district, where fashionable clothing brands have established a presence. In addition, many restaurants, bars and nightlife destinations are located in this particular area as well.

North of the business district is the spectacular Benjamin Franklin Parkway, a grand boulevard that begins at the famous LOVE Park near City Hall and continues northwest, through Logan Circle, and ends at the Philadelphia Art Museum and Fairmount Park. Designed in 1917, the Parkway is one of the city's earliest urban renewal projects and takes many of its cues from similar boulevards in France. Today, the parkway is the spine on which most of the city's museums are located.

• 39.954729-75.1684373 The Comcast Center, 1701 John F Kennedy Blvd. Opened in 2008, at 975 feet tall, the Comcast Center is Philadelphia's tallest skyscraper and the headquareters of the cable provider. The building features a public plaza with a gorgeous fountain display, a dramatic eight-story “Winter Garden” and an energy-saving “glass curtain” that wraps around the Comcast Center, allowing for a 360° view of Philadelphia’s urban landscape. The building has also unveiled a Sony Style Comcast Labs Store, which includes an “Interactive Technology Lab” that is open to the public. The lobby has garnered attention as a tourist attraction. At first glance, the north wall of its lobby appears to be a wood veneer wall, but actually, it's a massive 2,000 square feet high-definition LED screen that's just displaying a picture of a wood veneer wall. Wait a minute, and a dancing figure might appear on the wall, or the entire wall might fade out and be replaced with a photograph or a video show. The computer-generated images are so realistic, you’ll think they’re jumping out of the wall. With a resolution 500% greater than that of an HD television, the Comcast Experience is a remarkable technological and artistic achievement. The video wall, a giant HD video screen that is actually the largest four-millimeter LED screen in the world, is located right in the building’s publicly accessible main lobby, so everyone can enjoy it. Visit during the holidays for special seasonal displays.

Center City West has an active nightlife scene around the Rittenhouse Square area. As it's also one of the wealthiest neighborhoods, crowds here can be young, hip, and beautiful—or at least pretending to be—which leads some other people to gripe about how it's all turning too "tacky" and "Manhattan-esque." Depending on how you look at it, this is either changing Philadelphia for the worse, or this is the kind of scene Philadelphia needs to keep people from leaving for the actual Manhattan. Either way, this clash of cultures results in a larger range of options this side of Broad, from the dark, blue-collar dives to the super-ritzy cocktail lounges.

If you're in Center City during the summer months, be sure to take advantage of Center City Sips, a downtown-wide Happy Hour every Wednesday from 5-7PM where many bars and restaurants all participate in drink specials: $2 beers, $3 wines and $4 cocktails, and usually some selection of food specials. As it's right after the hump of the office work week, you'll see a lot of young professionals in business casual, and some places will get really crowded, but the prices are definitely right.

• 39.9477-75.168121 Monk's, 264 S 16th St (between Latimer and Spruce), ☏ +1 215-545-7005. One of two of the best places to drink beer in Center City (the other one is Eulogy Tavern in Old City). Monk's has one of the largest beer varieties in the area, especially Belgian beer, with the right food to go with it (the burgers and mussels are standouts). Check their website to see the newest featured beer. 
• 39.94777-75.166222 McGlinchy's, 259 S 15th St (between Latimer and Manning), ☏ +1 215-735-1259. One of the few true dive bars in Center City. It's dirtier than you can imagine, and since the lighting is dim enough to be almost completely turned off, it's also dirtier than you can see. Right away, the staff genuinely doesn't like you. You will be a smoker as soon as you walk in, whether you smoke or not; McGlinchy's is one of the few bars that is exempt from the smoking ban and it's obvious from the door. The bathrooms are tiny and completely foul. You're better off not washing your hands, just to avoid touching as few things in there as possible. Fights are not uncommon, but the staff is always quick to pounce and drag it outside; McGlinchy's does not suffer fools. But the beer is ridiculously cheap, and the staff will warm up to you if you aren't an idiot, don't waste their time thinking about what you want to drink, and tip well. The crowd is often a mix of old barflys, blue collar after-workers and plenty of cute art school students. This is hands-down one of the best bars in Philly if you leave pretension at the door and roll with the vibe. 
• 39.95073-75.169623 Raven Lounge, 1718 Sansom St (between 17th and 18th Sts), ☏ +1 215-840-3577. A small bar just around the corner from Rittenhouse Square that's a lot of fun.

Other nights there will be live music or a live comedy show as well.
