Where do you place a crescent salad plate in formal table setting and where does the B go?

You're likely referring to a bread and butter plate, not a crescent salad plate. Here's how to place it in a formal table setting:

Placement:

* Top left of the dinner plate. The bread and butter plate is positioned above and to the left of the dinner plate, slightly angled so the edge is closer to the dinner plate.

The "B" doesn't go anywhere: The bread and butter plate is simply used to hold the bread and butter, there is no specific placement for a "B" on it.

Formal Setting:

For a complete formal setting, the bread and butter plate is part of a larger arrangement:

* Fork: To the left of the dinner plate

* Knife: To the right of the dinner plate (blade facing the plate)

* Spoon: To the right of the knife (if needed for the meal)

* Water goblet: Above the knife

* Wine glass: Above the water goblet (if needed for the meal)

* Napkin: On the dinner plate (or to the left of the forks)

* Butter knife: Across the top of the bread and butter plate (optional)

Remember, the placement of these items may vary slightly depending on the specific meal and type of cutlery used.
