At Restaurants: When it comes to great service, "Hungary isn't quite there yet," says Kozlowski. "If the service is good, I leave 10 percent of the total bill in cash, tops. If it's just coffee, I leave pocket change."
At Hotels: Tip concierges about $20 if they do something extraordinary like secure you hard-to-get tickets. Porters get $1–$2 per bag, cleaning staff $3–$5 a day.
Guides and Drivers: Tip guides $15–$20 per person per day for small groups and $10 per person per day for larger groups; tip drivers half that. In taxis, round up the fare.
Dollars Accepted? Yes, if they're undamaged and crisp, and never give American coins.
P.S. Expect to tip train porters $1–$2 per bag. Spas will probably include a 10 percent service fee, but you can tip 10 percent on top of that.
