A buffet is a way of dining where you get to choose from a bunch of different dishes that are all set out for you to help yourself. The idea started with the Swedish "smörgåsbord" back in the 16th century and has since turned into what we call a buffet today. It’s all about self-service, giving you plenty of options and the freedom to choose what you want. Buffets are a fun twist on traditional dining! Instead of just ordering from a menu, you get to choose from a huge variety of dishes and go back for seconds—or thirds—whenever you want, as long as you stay within the rules. People really like buffets because they provide a lot of options, usually have that “all-you-can-eat” vibe, and create a relaxed setting. These days, you can find buffets in all sorts of places, like restaurant chains, hotel breakfast spreads, themed parties, and even event catering.
