Most restaurants in Bermuda will include the tip in your bill so it’s important to look over the bill carefully so that you don’t end up tipping twice.  I think generally the tip added is 15% but you can always add more to that if you feel the service was exceptional.

Also check your hotel bill before leaving because they may also tack on a 10% service fee, and you’ll probably want to tip taxi drivers about 10% of the fare.
