If you do chose to give a tip, the common rate in restaurants is to tip between 10% to 15%. Similar to restaurants, tipping bartenders 10% to 15% is the common range whilst tipping above 15% is considered to be a generous tip and best reserved for outstanding service. Unlike in many other countries, it is not common to tip hotel staff, though you can leave a tip for the cleaning staff who come every day to change towels etc, if you feel they’ve done a decent job.
