Kind of an awkward situation and I'm not sure how to handle it. My wife is having a big birthday coming up and I want to throw her a surprise party. She has a favorite expensive restaurant that she loves to go to for special occasions where we can indulge ourselves a little, and her expectation is that basically she goes there for every birthday celebration if we are in town. So I really don't have a choice in restaurant to hold a surprise party for her at.
We will have a party of about 12 people and while the restaurant is "expensive", about 80% of the menu is what I'd call "reasonable" but expensive. Meaning, we are fine paying for everyone's meals as long as they stick somewhere around the normal price dishes for the restaurant (around $50-$75 for an entree, so I'm not trying to be cheap here). The restaurant also has, however, a few other items that are considered luxury or even super luxury items (over $100, $200, and even $300 for an entree). While I doubt that anyone in the party would be so crass as to order one of these items just because someone else is footing the bill, I don't really know for sure (they are mostly her friends).
Is it completely tacky to put something in the invitations indicating that we will be paying for food and drink but excluding some of the bigger ticket items (basically caviar and Kobe beef)? Is there an "elegant" way to word it?
