Young Girl In The Kitchen

Other kitchen types
Restaurant and canteen kitchens found in hotels, hospitals, educational and work place facilities, army barracks, and similar establishments are generally (in developed countries) subject to public health laws. They are inspected periodically by public-health officials, and forced to close if they do not meet hygienic requirements mandated by law.
Canteen kitchens (and castle kitchens) were often the places where new technology was used first. For instance, Benjamin Thompson's "energy saving stove", an early-19th century fully-closed iron stove using one fire to heat several pots, was designed for large kitchens; another thirty years passed before they were adapted for domestic use.
