I've had to deal with this before. What I did was not use any flexpoints for the week and then I had the wghole 35 to play with. I figured that the worst that could happen was that my entree would end up being about 10-15 points and went with that.
I picked what I thought would be the least fattening dish, skipped the breadbasket, had them put any sauce or salad dressing on the side and decided that I could either have a glass of wine with dinner or dessert but not both.
It turned out okay.
