Not through the heating process in any way. Hob to cook some fish such as smoked salmon. Or vegetables or fruits, etc. Most of the cold kitchen is cooking salad or sandwich, etc. But there are some exceptions, like meat on a kitchen hot then. Whichever style of restaurant Some shops may open for just one evening. I will work about 2 pm to midnight. Some kitchens may work out in the hotel's Room service. You must have staff on standby 24 hours it will divide the work in shifts. It depends on the system but at that.
