Restaurant To Another World is a weekly anime. Even in real life, the door to Nekoya appears once every 7 days!
Season 2 aired on October 2, 2021, which is a Saturday (day of Saturn).
The diners frequently only choosing one specific meal each time they come to Nekoya can seems odd, given that you'd expect only having the one meal everytime would get tiring eventually. However, given just how long the time frame per visit being seven days, that makes each meal less at risk of becoming too tiring from eating it too often, and instead being more of a delicious treat every once in a while.
Alphonse Flugel's situation in his introduction is baffling given that you'd think that he could have told someone about his situation at any point during the last twenty years, and get rescued. The fact that there are several people from his own country who are also patrons, two of whom are a national hero who saved the world and a Duchess no less, who could have mustered forces to find him only makes this even more glaring.
However, it's entirely possible that he might have told them at one point, but the bigger issue was actually finding his location in the Other World. Even in the modern day, finding a person presumed dead and lost at sea tends to be extremely difficult, even when you've managed to narrow down the rough location. It probably would have been even more difficult in a medieval era fantasy world, where there are plenty of dangerous sea monsters and storms in a time when navigation and ship quality would have been severely limited by comparison. The fact that Alphonse ended up on a remote island also suggests that he likely landed in a place that wasn't properly charted, which would have added more complications to finding him. Finally, given they're not always friendly like Arius and Iris, and Fantastic Racism possibly being at play, it's not like they could just ask the locals about him either. Alphonse's situation, while certainly full of absurdities, turns out to be a bit more grounded when some consideration is given to the full circumstances and the society he was part of.
The light novels partially confirms this, as it's noted that he washed up on an island far away from ship routes, and thus had no way of guaranteeing being found or rescued.
Kuro has notably more developed transformation skills compared to her sister/comrade Red, not only changing into an Elven form with little indication that she's anything otherwise except to extremely perceptive mortals, but also being able to create clothes for herself. This stands in contrast to Red, whose draconic traits stick out even after transformation, and she still needs her aide to bring her a dress separately. However, considering that Red has to spend time defending/patrolling her territory and likely doing dragon god related duties, it's possible that she just simply doesn't have the time to develop and refine her skills to that degree. Kuro by contrast, being on the moon with no one else to bother her, likely developed her shapeshifting skills to a far greater degree simply because she had all the free time in the world to do so.
There's also the point to consider that Kuro is a threat to anyone weaker than her by virtue of merely being around her due to her Death powers. She is only safe to be around by lesser beings in her Elf form, explicitly having to repress her powers so they don't kill people even in that form. Thus she probably had to refine her magical prowess to a much greater degree to ensure that it remains that way. Red by contrast doesn't have as refined magical skills simply because she doesn't need to. She's dangerous to approach, but she doesn't need to be a threat so long as you don't provoke her, and she certainly won't kill people just by simply existing in the same area as lesser beings.
The novels also explicitly call her the "wisest" of the dragons, which would certainly give credence to the idea that she was probably far more adept at certain magics compared to her peers. Social skills, not so much.
Elves are apparently strictly herbivorous despite the fact that we see a flashback of Fardania as a baby breastfeeding from her mother.
Probably since Elf veganism is due to their connection to nature and refusal to eat anything from nature's creatures, breastfeeding doesn't count to them as being of Elf origin.
Babies are incapable of digesting anything but milk or something ridiculously similar (ex. baby formula). All mammalian babies, even otherwise herbivorous ones.
Aletta is only paid 10 silver coins per week working at the restaurant. Arte mentions she has 1 silver coin, which is barely enough for 2 meals. So Aletta can only eat 20 meals a week or 2.8 meals a day. This isn't enough for an adult and explains why she is constantly starving and rationing food.
Until you realize that she is only working one day a week, so she is really getting paid 10 silver coins per day. Her pay also includes staff meals, and she is shown working outside the restaurant as well.
One also has to consider that the meals costing 1-2 silver is only in regards to Nekoya's higher priced dishes. The average meal ranges from anywhere to free (depending on the situation) to a few coppers per meal at most, enough that even kids and teenagers can afford it with a little bit of work. Aletta notes in the light novels that in the Other World, most peasants can make around 10 copper coins for a day's work at most, and that 10 silver is enough to last her a month if she's smart about her money use. So if anything, the Master is paying her extremely generously for one day's work.
