Restaurant Tipping Guide
Maître d’/captain/sommelier: Extra tip only for special service, such as spending time on your wine selection (add 10 percent of the wine’s cost) or getting a choice table ($10–$20). These tips are seldom expected outside the U.S.
Parking valet: $2–$5. (Tip up front to ensure better service.)
Coat check: Opinions vary, but $1 per item is still acceptable, and $2 is better. In Asia, no tip is necessary.
