This classic 24-hour diner opened in Northeast Philly back in 1932. It has undergone a few changes since then, but today the Mayfair Diner remains a pure 1950s-era throwback for chicken croquettes, creamed chipped beef, and thick slices of pie.

Port Richmond was a treasure trove of traditional Polish foods, with Czerw's being one of the oldest surviving shops. It originally opened in 1938 as a store called Philadelphia Provisions, and has been smoking its own kielbasa for 80 years. On Christmas and Easter, expect long lines and early sell-outs.

Originally founded as a bread bakery in the 1920s, Port Richmond staple Tacconelli's didn't start using its oven for pizza until the end of WWII. That pizza is now so beloved that people from all over the city still flock to the out-of-the-way location despite a number of inconveniences, including the requirement to call ahead to reserve dough. That doesn’t dissuade the many fans of these thin-crust pies.

There's no shortage of must-try foods within Reading Terminal Market, open since the 1890s. The sprawling market houses a mix of Philly icons, Pennsylvania Dutch classics, and new favorites. Hit up Beiler's for doughnuts, dig into DiNic's famous roast pork sandwiches, and grab a cone at Bassett's (which is America's oldest ice cream company, founded in 1861).

Irish pub McGillin's claims to be the oldest continuously operating tavern in Philadelphia, having opened its doors on narrow Drury Street in 1860. Today, it’s a popular venue from early to late and celebrates every holiday — big or small — with gusto (and themed drinks, food, and decor).

Philly would be nothing without its dive bars and Dirty Frank's is a prime example, chugging along at 13th and Pine since 1933. Originally just called Frank's, and at one point misguidedly renamed 347 bar, Dirty Frank's was a nickname that came along with the bar's second owner and stubbornly stuck. Thanks to cheap beer and citywide specials, it’s a popular hangout for a wide variety of characters.

As the story goes, Ralph's originally opened in 1900 at 9th and Montrose before the Dispigno family made the short move to their current location in 1915. And it remains in the family to this day, serving red gravy Italian-American staples that have long been the backbone of the Italian Market neighborhood.

Founded in 1899, Dante & Luigi's is a South Philly classic known for its Italian-American food. It’s more upscale than its nearby competitors, with white tablecloths, chandeliers, and more formal service, but it’s never stuffy. The storied spot was the scene of an attempted mob hit in the late '80s.

Tenth and Christian is typically one of Philly's best-smelling intersections, thanks to Isgro. Holding court since 1904, this tiny shop fills up quickly on weekends with shoppers seeking out cannoli, butter cookies, rum cakes, torrone, and more.

Originally opened a century ago, Palizzi was designed as a members-only joint, serving cocktails and food in a South Philly row home to immigrants from Vasto, Italy, and their families. Last year, chef Joey Baldino — of local favorite Zeppoli in Collingswood — inherited the club from his uncle. Palizzi is still members-only, but Baldino broadened the criteria to allow more diners to enjoy spaghetti with crabs, calamari with peas, and escarole and beans in a charmingly retro space.

One of South Philly's best-known and most-beloved bakeries, Termini was established by two brothers in the 1920s. It’s all about the cannoli here. The shells are handmade and filled to order with vanilla cream, chocolate cream, or — the real deal — ricotta with chocolate chips.

This circa-1935 diner is still going strong and providing South Philly with a 24-hour haunt perfect for devouring a pork roll, egg, and cheese sandwich early morning, mid-afternoon, or late night.

Opened in 1938, the original South Philly Nick's is a perfectly cozy cave full of inexpensive beer, roast beef and turkey sandwiches, and can't-miss gravy fries.
