There have been a few attempts at "all you can eat" restaurants in my town. I went once with some friends to one of them an ate 8 pizzas for 9€ aprox. And that's what I ate, A friend ate a whole tray of shrimp(23€/kg) and small lobsters(15€/kg) and the others did not fall behind. I guess the idea was to make a profit from the drinks(under 15c/unit provider to 2€/unit customer). It did not go well

The one that lasted the longest as such closed after 4 months, the rest reinvented themselves as "all you can eat" one day a week from 8AM-11AM and normal restaurant/buffet the rest of the time or similar patterns.
The closest one I know of is 1 hour in car away if you take the highway, 3 hours through the old road, which in Europe's distance is VERY FAR AWAY.
All the "All-You-Can-Eat" restaurants I've been to have a pretty hefty upfront price. Like there's all you can eat steak for $50-60, or Korean BBQ for $70. Since it's all meat most people can't actually eat enough to eat more than the wholesale cost of the food. Or alternatively it's something like Sizzler where the buffet food is all cheap food.
Yeah there has been plenty of buffet type restaurants that pop up in my area and yeah not a lot of them last long. There is this one tho that's been around for 5-6 years. They have all sorts of random stuff to. Even someone who makes all sorts of sushi
Here these types of restaurants are already part of the culture. Sushi, pizza, barbecue, pasta, crepes, mini burgers and appetizers, asian, arab/lebanese, mexican and many more. There was even some milkshake all-you-can-eat at one point!
I eat a lot, but most people don't eat that much, I think one of the "charms" is the variety. You can eat a little of each instead of buying a single big plate, and also most of them charge for the drinks, so there's profit.
There are tons of these restaurants where I live starting as cheep as $10, but the average is between 30-$60, depends on the quality of the food. Some of them even have children free. Only the adults will pay. As far as I know these kind of restaurants have been working here from forever. Even if some people may eat like tomorrow is going to be the zombie apocalypse, most of the consumers are not that desperate.
Tthe ones in my area are usually slightly more expensive than à la carte, but like I said, one of the charms is earing more variety. (But people like me and my friends do get ours money's worth, we eat a lot. Hahaha)
Ducks are actually very tasty just saying.
Never ate it. I heard people praising duck à l'orange, I've always wanted to try it.
And I'm kind conflicted towards foie gras. I know it's cruel, but it also looks good.
I checked online, out of curiosity, how they are doing. 7 locations at 20$ the all you can eat buffet(I think they had 3-4 before), except for the Asian one that's 30$.
Doing pretty good and still affordable, but people complain on reviews that there are not enough waiters in the all you can eat buffet to do their biding and they have to move their ass if they want something
Some of them, like the barbecue ones, usually you serve your food at the buffet table, but most of them you have to wait for the waiter. Usually it's okay, but I had experiences when there's wasn't enough of them, or you asked for food and it took a long time. In a sfiha (lebanese food) all-you-can-eat one time I ate less than 10 of them, even though I certainly could eat like 50. We asked, asked, asked and the food never came.

We complained to the manager and at least they gave us a takeout box with some some of it (which obviously they don't do in these types of restaurants). It was less than I could've eaten if somebody bought the food, but still better than nothing.
But I also heard compliants that were like very, very, veeery dumb and obvisouly the client was at fault.
Looks like it, but I neither code nor am I a game dev, so I'm a noob. Is it called a renderer or an engine?
Neither, I think. Honey Select 2 is a game by Illusion with character customization (and lots of mods) and a studio mode, where you can free pose characters and such, so many use the game as a Render Engine to take pictures and videos.
Ren'Py is usually the game engine in games that use Honey Select, Honey Select 2 and Koikatsu images. It's what is responsible for the game logic, showing images, text and such.
