By definition, the breakfast table is simply a place to consume the first meal of the day, according to the website wordnetweb.princeton.edu.
Breakfast tables are usually smaller in size compared to kitchen and dining room tables. Breakfast tables normally seat two, four, or six people.
There are tables, and there are nooks. Some nooks have just the table with a bench, and some are a booth style. Wordnetweb.princeton.edu defines breakfast nook as a place to have smaller meals.
A formal breakfast table consists of a specific menu, fruit, cereal, toast, marmalade, eggs, and meat. Coffee in a silver serving pot is properly placed in front of the hostess, according to "Table Service," by Lucy Grace Allen.
Small apartments and small meals are good reasons for having a breakfast table in the kitchen, as described on Treehugger.com.
