Unfortunately not Blue Eyes, but my mother was Polish and made pirogis to die for,
I would pop them like Smarties, until in my early 20s I went from a 30 waist to a 32, I eased up on them then.
Having Gallic blood I know my way around a good menu and wine list, so I frequently take my wife to dinner at good restaurants, The Ledbury, Notting Hill, Elena's L'Etoile, Charlotte Street W1.
I don't know where you live, but if you like Polish or other Eastern European foods, try Baltic in Blackfriars Road SE1, a gazillion different vodkas.

I agree with others who have said just ask her what she wants.
But a question on my mind is what sort of presents does she get you?

Men will never unravel the mysterious workings that go on in a woman's mind, just ask my husband.

If she asks for suggestions I almost always say book tokens, but on quite a few occasions in the past, when she knows that it's on my mind, she'll spring for a Lufthansa round trip ticket for me to visit my son and grandchildren, (from my first short-lived marriage), they live in Bielefeld, Germany.

Sounds like an ungrateful mare with an attitude, least you thought of her and got her a ncie gift.

Silk is akin to nylon for me, especially when feeling hot and sweaty due to my body having a mind of it's own.

She sounds like hard work. Mine would be delighted with such a gift. We always take the mick out of one another, if she's putting make up on and I say 'you can't polish a turd' she would laugh, as she knows my sense of humour.

Me and my OH have this arrangement where he forces me to write a list (which I hate because I'm not the kind of person who likes to make demands for gifts). I also pepper my discussions from Sept onwards by saying 'ooh, I like xyz' or 'ooh, I need a new...' (Dec birthday and Christmas at the same time). He then ignores the list because he doesn't like the idea of just getting me something I've asked for, and manages to completely miss all the things I hint that I'd like.

He then just works out what to get me by himself, with results as variable as some lovely jewellery to a series of weird looking toys.

It certainly sounds as if you care and have tried to get her something she would like, and also that she didn't respond in the most gracious way, but I for one would find such presents a little generic - i.e. the kind of thing that the advertising industry, magazines etc, assume women want. Some do I am sure. I love a day out at a 'spa' in the sense of Bath spa, with outdoor swimming and jacuzzis etc. in a beautiful setting, though I'd want my partner or a friend to be there too to make it fun.

You have been together a long time. You must have got her lots of presents in the past. I think most people, which includes women, appreciate presents that show that someone knows you and knows the kinds of things you like/like doing. The flights to Germany sound like a clever present. If someone likes art, tickets to the Matisse exhibition? If theatre, then to a good production, or a concert or gig? A footlball match? WImbledon tickets (bit late now I suppose ..).

Granted that my OP made her seem like an ingrate, but she isn't really like that.
It was my fault for laying it on too thick in my OP I guess.
I was p***ed off that she appeared to be less than happy with the beauty parlour voucher, but I now believe that it was her rather low self esteem that triggered that.
The thought of some mid twenties Cara Delevigne look-a-like beautician seeing her little roll of a spare tyre no doubt put her off the visit to the spa.
The discomfort of the onset of menopause, coupled with my trademark thoughtlessness in buying her something that would cause her to perspire more, probably pushed her over the top when she opened the gift box and saw the silk PJs.
