Why this spelling
This romanisation is not the spelling copied letter by letter. It is built from the National Institute of Korean Language’s Revised Romanization, which writes what the word sounds like once the sounds next to each other have changed it.
When you would say it
Say it as you walk in, before you sit down, and hold up two fingers.
Portions, and why two people can’t order one dish
Plenty of Korean dishes are cooked and priced by the person, not by the plate. A stew, a cut of barbecue, a hotpot — you order "two portions" and it arrives as one shared vessel sized for two. So two people ordering a single portion often get turned down, and it isn’t rudeness: on that stove, the dish simply doesn’t exist in a one-person size.

The guidebook prints these as numbered cards, so you can hold up a number instead of trying to pronounce it. The Korean edition comes with it and has the same numbers in the same places.
