The wealthy people I know ( and I know lots of them through work ) generally employ full time private chefs.
This means everything is really really good, professional chefs can do much better when they cook solely for 2-4 people - catering to their personal tastes-- than they can for the lunch crowd at a fine restaurant. I am reminded of the movie “First Wives Club”, there is a scene when the bimbo has lunch at the home of the wealthy society lady and makes a totally gauche mistake by referring to the salad as “restaurant quality”.
I once saw the chef at a home make a grilled cheese sandwich for the family’s 5 year old son and it looked so good I was tempted to snatch it from him.
And a lot of the food they make is very healthly and low calorie, that how some of this rich ladies stay so thin. I could drop a lot of weight if I had a professional chef to think up and execute yummy low calories recipes heavy on the ingredients that I really like, with no ingredients that I disliked ( you don’t get that at any restaurant ).
But still…what do these folks consider a luxury meal…surf and turf? I think not, it would be considered rather low class ( for the cruise line rabble), although some of the husbands may secretly crave it.
More likely they are going to a fine restaurant like Per Se or French Laundry for those special meals ( or having something similar prepared for them at home and they are enjoying dishes like these below on those special nights.These meals usually consist of small portions and many courses – excerpts below are from the menu at Per Se
