What do some galleys have that others may not?

Some galleys may feature locking cabinets, which are designed to securely store supplies, equipment, or sensitive items during flight, especially on aircraft that operate in various conditions or for different airlines. This security feature helps prevent unauthorized access and ensures that items remain safe and organized.

Locking cabinets are particularly useful on flights that may experience turbulence, where loose items could pose hazards. Not all galleys are outfitted with this feature, as it can depend on the airline's specific needs, the aircraft model, or the intended flight operations. In contrast, while heating elements, refrigeration units, and inbuilt security systems are important, they are often standardized or required across multiple aircraft types or routes and are less likely to vary between different galleys within a fleet.
