Currency, costs, and tipping
Take cash (in small denominations), an ATM card, and a credit card with you. Travelers' checks are becoming obsolete. The easiest currencies to convert are US dollars and Euros, and exchange offices give the greatest prices. There are several ATMs across Turkey, however verify with your own bank about international withdrawal fees before going. Always have cash on you in case a machine that accepts your card is unavailable.
In Turkey, good service is expected, but wait staff are underpaid, so tips are appreciated; 10-15% is standard in fancy restaurants, but people often leave something at small, family-run neighborhood eateries. For taxi drivers, round up the fee or add an additional US $1-2 (8.40-16.80tl) if they assist you with your luggage. This currency conversion is approximate because the Turkish lira is extremely volatile at the time of writing. This is one of the top Things about Turkey You Should Know before traveling to this beautiful country.
