Souplantation
In short
A US-based chain of all-you-can-eat buffet restaurants that originally operated under the name Souplantation.
In plain words
It is a restaurant where customers pay one price to eat as much food as they want. Most locations serve salads, soups, and various hot dishes in a self-service style.
A simple example
A customer pays a fixed fee at the entrance and then walks along a long counter to fill their plate with different salads and pasta dishes.
Why it matters
It helped popularise the salad bar concept in American dining. Many locations rebranded to Sweet Tomatoes to create a more modern image.
Easy to mix up
Do not confuse it with a plant nursery or a shop that sells only vegetables.
