Taiwan - Taipei
Tipping Etiquette

At Restaurants: Check the bill; about half the restaurants include a 10 percent service fee. If yours doesn't, leave 10 to 15 percent in a top restaurant and 10 percent in a regular one, says Judy Swen, owner of San Francisco's Lassen Tours, which books trips to Taiwan.

At Hotels: You may tip the concierge $20 or so when you check in or out of the hotel, cleaning staff $2 per day (left in the room), porters $1 a bag, and doormen $1 to $2 if they call a cab.

Guides and Drivers: Tip 10 percent of their fee.

Dollars Accepted? In Taipei, yes; outside the cities, tip in the local currency.

P.S. "They don't have tipping in the culture, but if you tip people, they'll be really happy," says Swen.
