Q:

No, he was not wearing a wig

It may be a bit of an overused trope, but my husband-to-be took me to eat in a nice restaurant for my birthday. When we entered the restaurant, I had a strange feeling that this was something I'd seen before... Then I remembered that I had applied for work in the restaurant a few years back, even sent them my CV and everything.  
The dinner was excellent – we had wonderful small appetizers, enjoyed some premium beef cuts, tasted some Rhone valley reds, and had coffee with milk afterwards. The only thing I have trouble remembering is what exactly we ordered for dessert.

Can you guess what we had for dessert?

A:

For dessert, you might have had

 a gateau St. Honoré, or a marron glacé, or perhaps some delicious crème brûlée.

Let me tell the story again.

 (No, he was not wearing a toupée.) Despite the cliché, you and your fiancé went to a nice restaurant. You remembered sending them your resumé. You had some canapés, ate (perhaps) a filet cut of beef, drank (perhaps) some Beaujolais wine, and then enjoyed a latte.

[EDITED to add:] OP has explained in comments that in fact

 the actual intention was "words with diacritical marks" rather than specifically requiring e-acute or specifically requiring its sound to be at the end of the word. That resolves the single thing I was least happy about (the wine: Beaujolais is made near but not in the Rhone valley) as well as enabling better answers for the steak and the coffee.

A:

Je pense que c'était...

 un parfait.

All credit to @Gareth McCaughan's excellent answer in spotting the pattern, this only really builds off of that (hopefully not too much steals off that), combined with it being, perhaps, fitting the "an overused trope" bit a little (although, granted, so does part of his answer, in the context), along with the mix of something that is also a common word in English... and because, forgiving the pun, it's the perfect finish. But at the same time, the word, while a borrowed word in English, has an actually different (still close, but not the same) meaning in English, which would easily explain the forgetting/confusion.
again, building off of what Gareth spotted, this would have been my rendition in that vein:

 No, he was not wearing a toupée. Despite the cliché, your fiancé took you to mangé in a [nice restaurant {this feels like I should have a word for this, but the only thing coming to mind is to simply use italian, rather than french, and then the pronounciation is falling rather than rising at the end... unless the twist is that it's a restaurant à Nice}] for your birthday (tanti auguri a te). Upon entré, you experienced some déjà vu, but had rappelé that you had previously appliqué for a position d'emploi, including sending them your Curriculum Vitae. You had lovely canapés, enjoyed chateaubriand filet, goûté des Beaujolais, and finally ordered some café au lait.
