As for the largest meal... That's an easy one...
Steve and I went to Disneyworld a couple of years ago. I made reservations at Victoria & Albert's in the Grand Floridian Resort. I had first hoped to get the Chef's Table Seating, but when I had made the reservation - months in advance as suggested - the Chef's Table (which is literally in the kitchen) was already booked. Ah well... Sitting out in the intimate dining room would be fine too.
The morning of our meal, I received a call from the restaurant asking if we'd still be interested in the Chef's Table since someone had cancelled.... YES!!! So...
I forget the exact number of courses and exactly what we ate, but it was a LOT! At least seven courses, plus I splurged on the wine pairings. -A different bottle of wine came to the table with each course - including dessert. And we were treated to a bottle of champagne to start off the meal too! *They give you a customized menu, and I do have that in my keepsake box, so if I ever dig it out, I'll post our repast here. There was a plate of
amuses bouches to start off with... Then a soup... Then a salad... Then a meat course - I remember something with crisped sweetbreads (yum!)... Then a fish course... Various vegetables...
However, the one thing I do remember was that the chef was being very generous with us. Since we were seated in the kitchen, we were allowed to remove our jackets, and we were also allowed to ask the chef's and his assistants about the food they were preparing, and walk around if we liked. Well, being the son of parents in the food-service industry, as well as an avid cook myself, I had lots of questions. And they had lots of answers for me. Some of the "answers" came in the form of entrees that were developed just for us since I had asked about certain preparations and ingredients. They would also give Steve and I different plates of food so that we could sample basically everything on the menu that night. However, the piece de resistance was dessert... rather dessertsssss. They gave us one of each the chocolate desserts they were preparing that night. FOUR or them. And then came the handmade chocolates with the final coffee service... Whew! *And the coffee was prepared in a vacuum pot - very cool!
It was our last night in the Magic Kingdom, and we had originally planned to go out for a bit after our dinner. Well, we just ended up back in our room lying in bed, both of us with very full stomachs, and very "full" heads from all the wine... And that's all we did our final night in Disneyworld.

But it was soooo worth it. -And, actually, at that time, the Chef's Table seating with the wine pairings was running about $140/person. Not exactly cheap, but after all the food we were served, and all the wine(!)... It ended up being quite the bargain. -We even tried to buy a bottle of the champagne they served us once we got back to Richmond... It was $120/bottle at our local Wine Superstore! *And they even sent us back to our rooms with the remaining half-bottles of wine, as well as a box of the chocolate truffles.
