In the UK at least, there is a thing called a “fish knife” which is part of fancy cutlery sets.
This is for eating fish, of course, not gutting or processing it. I have used one occasionally, but it doesn’t seem to have any real advantage over a normal table knife.
Gee, I don’t recall ever getting a spoon at a restaurant unless you order soup. Then the spoon comes with the soup. Standard to me is knife and fork, better places have two forks.
My wife is Thai and they eat with a spoon. Just a regular tablespoon. The Asian style spoons are for soup. Chopsticks are for noodles. Everything else, just a spoon. I’m totally used to it.
In my experience, at “sit down” (table service) U.S. restaurants, the standard is typically a dinner fork, a table knife, and a teaspoon; fancier places may also provide a smaller fork (salad fork/dessert fork) as part of that standard place setting. And, if you order soup, they bring a soup spoon along with it.
It depends on what sort of restaurant you’re talking about and to some extent the meal - whenever I have breakfast at a restaurant, even a diner, I get a fork, knife and teaspoon. For lunch or dinner at a casual restaurant (something like Outback or Applebees’s but not necessarily a chain ) , it’s usually a knife and fork and they bring you a spoon if you order something that needs a spoon ( like soup or coffee). The next level up from a casual restaurant , the setting is a knife, fork and teaspoon.
Ah, I guess I have never been to one. We do eat at the local Brown Derby every month or so. No spoon. Two forks. To me a steakhouse is the quintessential restaurant.
Based on the OP, I thought this website might have the answer to the initial question. While it does not get into nuance of fine cutlery in restaurants that the thread went toward, it is pretty interesting nonetheless:
I finally cracked down and did an informal “IKEA-test” as well. Looking at the 8 first results given when opening “cutlery sets” on local ikea pages I get that:
US and Mexico IKEA-shoppers are presumed to be two fork buyers. Norwegian, Swedish, French and UK shoppers are presumed to mostly want one fork cutlery sets. And Chinese IKEA-shoppers are presumed to want a two fork set, or sets of just chopsticks or just spoons.
Of course who shops at IKEA might be different in different nations.
