If the kitchen were a person, it would be the tough multitasker of the group. A lot of tasks get done in a kitchen—from preparing ingredients to serving food to dishwashing. This versatility is the primary reason every establishment would benefit from having its own pantry or kitchen. A manufacturer of stainless kitchen cabinets explains the different spaces that should be installed with the best kitchen they could have.
Private residences would be the first thing to come to mind when you think of kitchens. After all, parents helping their kids learn to bake or cook is a famous scene in pop culture. The kitchen is where you do daily household duties like making meals for the family.
Some student dormitories have kitchens that are usually managed by in-house staff. Students could use the kitchen fridge or cabinets to store their food supplies while getting limited access to the cooking amenities.
Restaurants, without a doubt, would need specialised kitchens that can accommodate the cooks as they prepare batches of food for customers. The fridge would have to be large enough to store many ingredients, while the tables and tools should be sanitised to ensure the food served is clean.
Hotels would also need kitchens because they would need to feed guests staying for consecutive days or weeks. Like restaurants, the kitchens of hotels would need to be industrial-size for employees to be able to prepare lots of food at any time of the day (or night).
Kitchens can be considered a hot necessity because of the sheer number of tasks you can do in it. Baking, cooking, dishwashing, and such can be done once a place has its own kitchen.
