Working in a restaurant kitchen is much different than working in a kitchen in your home. The reason is that you are prepping a lot more food, and with more prep and more food comes the need for more space. This is especially true when it comes to sinks. If you have a single sink in a restaurant kitchen you may find it difficult to add water to dishes, rinse fruits and vegetables and peels other items.
As such, compartment sinks really are the best option for any restaurant. They will allow for the multitasking that is a must in a restaurant and will also allow the kitchen to remain as clean and as organized as possible—even the in the midst of preparing all of food for any given day.
