The cost of living in (and therefore eating in, entertaining in, and generally visiting) Philadelphia is known for being ever-so-slightly more reasonable than New York, Washington, D.C., and other international cities. On the other hand, just by virtue of its location in the Northeastern United States makes the region more expensive than most places in the world. In other words, you can find a burger in Center City for $4. And another for $24. ATMs are prevalent in Center City; if you don't have an account at the bank sponsoring the ATM, you'll pay up to a $4 fee for a withdrawal or transaction.
The adage "cash is king" is mostly true in Philly, too. You'll definitely want a few dollars on hand if you're planning to hop a bus or subway, which accept tokens, passes, or exact change only. Most cafes, grocers, and stores accept all credit cards. The one notable exception: BYOB restaurants. Many are cash only.
Beware of hidden credit card fees while traveling. Check with your credit or debit card issuer to see what fees, if any, will be charged for overseas transactions. Recent reform legislation in the U.S., for example, has curbed some exploitative lending practices. But many banks have responded by increasing fees in other areas, including fees for customers who use credit and debit cards while out of the country -- even if those charges were made in U.S. dollars. Fees can amount to 3% or more of the purchase price. Check with your bank before departing to avoid any surprise charges on your statement.
