Satisfy your sweet tooth on a 2-hour underground donut tour of Philadelphia. The sugary culinary walking experience is perfect for families and foodies alike. Stop at four of the city’s top spots for fried dough, including Federal Donuts and Beiler’s Donuts. The tour is also a great opportunity to orient yourself to the city, with stops in South Street and Reading Terminal Market.
This tour seems mostly to be Neil's creation, and it's hard not to respect his enthusiasm. I think he's still getting the hang of it, and some of his facts are better than others, suffice it to say. The donut portions are generous, that said. And if you're traveling with kids, they'll eat up the "certified donut afficionado" thing, too. Overall, great and extremely personable tour guide and tasty donuts. Don't hesitate.
