Tipping & Etiquette

Recommendation: 18 to 22 percent customary and expected in restaurants and bars. Waitstaff rely on tips. Add your tip to the receipt or select the percentage on the card terminal.

Power Sockets & Tap Water

Plug Type & Electricity: Type A & B (120V, 60Hz – travel adapter and voltage converter for 230V devices required!).

Tap Water: Drinkable in almost all areas, though often has a slight chlorine taste. Filtered or bottled water recommended for sensitive stomachs.

Insider Tip: A tip of 18–22% in restaurants is virtually mandatory as server base wages are low. Retail prices are always displayed without local sales tax!
