if you are sure you would enjoy it, absolutely go for it - most research shows that experiences remain in our memories longer than physical gifts.
However (as it sounds like you are doing), make sure to do your due diligence. I like really good cooking too - but have realised that simple food, cooked well, with little fuss, and often cooked by myself is much more enjoyable. I am a single parent, busy life, limited budget, so I rarely get an opportunity to eat out anywhere, let alone a very expensive restaurant. However, two summers ago, I was treated to a very very expensive meal in a particularly fancy restaurant, by my brother. We were joined by my SIL's brother and he made much fanfare of the food, the tasting menu, the wine. I enjoyed it less and less as the meal went on - the food was special, but I forgot it fairly instantly, and it felt like style over substance to me (this restaurant is really highly regarded, so it's really just me).
But the main issue was the price - I wasn't paying but the bill was obscene - over €2000 for the 4 of us. (The others at the table ended up getting various cocktails, aperitifs, after-dinner wines and what-not, and the drinks portion of the menu got significantly increased). I couldn't justify spending that kind of money - even though I didn't!
About a week later, the DC and I ate in a well-regarded pizza restaurant in a small town where we were on holidays and I realised I enjoyed that so much more - amazing flavours, gorgeous pizzas, lovely wine and all very relaxing.
I mean, it sounds like you will really enjoy this so do absolutely go for it, just choose the type of food you know you will love.
