I could handle the big-bucks Disney restaurants very economically by drinking water and eating only an appetizer.
What fun is that?
I spent $50 on my own dinner at Jiko last month, but I had two things off the appetizer menu, a dessert, and two glasses of wine. By narrowing my choices down to one appetizer (which is all that really was necessary, I had the tower of tuna and it was plenty large enough for me) and leaving out the wine, I would have cut the bill considerably. But it wouldn't have been as much fun.
I do not eat out at home and consider the Disney restaurants to be a splurge.
