What foods make you feel like royalty when you're eating them?

I'm British and grew up in the 90s, so I'm therefore conditioned to think Ferrero Rocher is the single fanciest thing on the fucking planet despite knowing full well there's no way that is the case.

Gimme that pyramid of foil-wrapped nutty chocolate spheres and I will be a king

I feel the same way about Viennetta ice cream.
- I used to think that, but I somehow felt more poor when I actually ate it.
Damn that's so true. It's not even that expensive of a candy and you can buy it everywhere yet still it feels like a luxurious rarity. I guess that bastard Ferrero knew what he was doing.
Not grey poupon?
That ambassador, eh? He's spoiling you.
But ser! Wizz theez Rocher, you arr spoiling us!

Eating a whole rotisserie chicken with my bare hands while drinking wine out of a goblet and tossing the bones onto the floor for the dogs to fight over as entertainment.

Cooked chicken bones are bad for dogs.
- It’s good to warn people against feeding their dogs chicken bones irl but in my scenario, these are tough mutts that know how to chew the bones properly before swallowing.
- They're dangerous because they splinter but since OP said dogs (plural), they probably just swallow them whole.
Spoken like a true Baratheon.

Eating grapes one by one

Any savory dish that has pomegranate seeds in it

- We all love to party - especially you, hedonism-bot.
I can't help but hold the bunch over my mouth and pluck one off from beneath.

That sounds delicious not gonna lie.

I avoid meat now due to its links to climate change so I’ve been on a journey food wise. Dal Makhani is just so decadent it made me so glad that I was born period. It’s a black lentil curry that is so fucking good i will devour a bowl in no time flat

There was a place near me in college that would make the special black lentil dal only on Thursdays for lunch, but it was always so good. I don’t know if it’s the same thing, but those lentils certainly made me realize I could be vegetarian.
Sounds like a delicious dish that overindulgence will ruin your day.

Grapes straight from the bunch, held overhead while lounging on a chaise

Not so much the food itself, but the entire package made me feel like royalty...

I was visiting Singapore last year for some work-related stuff. My coworkers were busy handling their respective areas, and I was mostly there for some related IT stuff that involved a lot of waiting.
I've always liked sushi, so I decided that for once I should try eating it at what seemed like a decent sushi-place not far from the hotel - I had pretty much all day to myself. So I headed down there.
For starters the place itself was amazing; It was small and cozy, with ne guy behind a counter chopping and preparing fish. The wall behind them was covered in knives of all sorts, manufactured by a childhood friend of the chefs. I was up front to the waitress about the fact that I wasn't really a sushi connoisseur, but I generally liked Maki rolls, Nigiri, and I was looking for a nice and filling lunch. So she recommended this one item in the menu for me that consisted of a little bit of everything.

The lunch ended up being more of a multi-course thing, and while I was eating one part, the chef was already preparing the next part. Sure, it was really good, but the attentiveness of the staff to give me a wonderful lunch added to it as well, explaining along the way what I was eating and what the actual Japanese name was (they were all Japanese, by the way).

It was pricey, but not insanely so. The experience was well worth the cost.

EDIT: Found the place: https://maps.app.goo.gl/8GoXqKNqgJ5bT7LZ9
I highly recommend a visit if you ever get the chance.

Those giant turkey legs they sell at ren faires.

To a lesser degree, juicy cherry tomatoes make me feel like Denethor. Juice dribbling down my chin "wrong kid died..."

Ren Faire turkey legs were SO GOOD. I miss them, and I miss the full-contact jousting knights, who were all certifiable but very fun people.

Pouring olive oil over anything makes me feel like a bit of a rich slut.

Work bakers hours at walmart most likly means put frozen doaugh in an oven then hit the auto cook button.

This is correct, but you still have to get up super early.
- Joke is on you, metheads never sleep

Steak and some kind of berries-- strawberry, blueberry, kiwiw, whatever. Something about tossing a raspberry or something in your mouth between bites of filet mignon is just so damn aristocratic

Expensive chocolate, cheese platters and when I order fish-based meals from Gousto (ordered a creamy linguini with monkfish medalions once and felt like a queen)

A really well cut mango is heaven.

I like to go to Trader Joes and buy about a dozen cheeses and make a Cheeses of The World board. Apricot jam and honey add extra fanciness.

Grilled cheese in a grilled cheese sandwich because it is in bread.

Single origin chocolate (not even very expensive, but only royalty had easy access to cocoa until recently and they didn't make chocolate the way we do now).

Nice citrus fruit.

Good quality Fourme d'Ambert, Cantal or Sbrinz

Quiche
Cream puffs

Salmon roe, sour cream and red onions on a slice of bread.

Quality chocolate!

Also the opera cream latte at the kidd!

Well-seasoned rare steak with a little butter melting on top.

A juicy mango.

OP, my adult daughter came to my house one day and I offered her filtered chilled water and fresh baked sourdough with butter - fanciest bread and water ever. Bread to me is magic, I make sourdough only so it's literally made of flour, water, a little salt and time. How does it get such flavor?

Anything with courses feels so luxurious to me. We don't eat that way in my house because we (mostly I myself) cook for ourselves and want to sit together to eat. Getting served small plates in succession is so labor intensive and also a nice way to eat. We did this at a small fancy restaurant once - we ordered several things and the waiter served them one at a time, for us to share. Best ever way to eat as a couple or small group.

Salmon, pistachios, cashews, fresh berries. Still wild to me that I can afford them as an adult.

Salmon

I worked on one of those fish farms in '91 : floating clusters of nets holding salmon raised to be sold, etc.

Mortalities were worthless, even the super-fresh ones. The morts would be dead but their gills would still be pink, so you know they were fresh.

On discovery, all work would pause. One person, with the speed and care one would give an organ donor, would ferry this mort and any others off to the adjacent farm with the smoker someone built on the detached workshop section.

Fresher than fresh, this poor fishy would be cleaned and prepped and in it would go. When she and her friends came out, it was amazing salmon.

Good times.
- I bought a pack of trader joes smoked salmon to take to a brunch last weekend but I couldn't end up making it, and I ended up eating the whole thing myself over a few days.
  
  It was a revelation.

Durian. Truly food for the gods.

Grilled lobster with garlic butter is a close second.

When I make my steak sandwiches.

I use fucking rib eye for a steak sandwich, fresh sourdough, cracked pepper infused aged cheddar, red onion jam... its absolutely glorious

Red onion jam sounds intruiging
- Its stupid easy to make and sounds fancy as hell. You basically take a metric assload of thinly sliced red onions (use a mandolin. More consistent = more better) and cook them over a low heat stirring pretty much constantly until they are the consistency of jam. Most recipes call for red wine vinegar, or red wine and balsamic vinegar but I hate wine and balsamic takes over IMO so I use a little maple syrup and apple cider vinegar. If you season it correctly its amazing.
  
  Problem is that its a bit of a time sink to make so you wind up making huge batches because its the exact same amount of work.

Ah, a giant bowl of red

Espresso. I just feel like I'm above all the plebeians.

Warm garlic bread

Artichokes

Peasant Soup.

olive tapenade on fresh bread

Eggs Benedict. With cracked pepper and a few drops of Tabasco. Like a steel or oil baron.

Anything when I get out of the hospital after getting the all clear about a collapsed bowel.

At first I wanted to say sushi, but basically anything I order online, because they're so expensive. But during those few occasions I really feel like royalty.

Grapes

Sachertorte. If it's a real good one, then I know it has been a looot of work to make it.

Probably Cordon bleu.

Filling a cow with it's own milk and some pig just seems like something a monarch would come up with.

Burger King?

Sashimi and prime barbecue cuts.

Things that take a lot of human skill or effort, in addition to being very flavorful. Like perfectly sauteed scallops with a complex sauce or basically anything with pearled onions. There's some Indian curries that have blown my mind too. The greater the variety of complimentary flavors experienced with each bite the better
