Is the tip to the tour leader and restaurant included?
The gratuity to your tour leader is not included. Consider him/her as you would others in the industry, or as servers in restaurants, cab drivers, etc. You tip them at your discretion, and a good time to do so is after the tour, when you are saying farewell. The tip at the restaurant is included with your tour cost but if a server is extraordinary, s/he will always appreciate a little bonus.
