Disneyland is the only place I have seen restaurants include tax. Only reason I have even paid attention is that I am on the board of directors of a civil group that meets for lunch, and we have used three different restaurants in the past few years. We have between 40 and 100 people per lunch. The current restaurant does NOT add automatically add gratuities, nor did the one before. But the restaurant we used until before those two did, and they calculated the 18% tip on the total AFTER sales tax. That can add close to $20 to the tip just on the sales tax on a $1,000 tab. And tip is supposed to be calculated only on the cost of the food, Our Treasurer always made them recalculate it to reflect no tip on the sales tax portion of the bill.
