Should Korean barbecue grills use electricity or gas or carbon?

When choosing a Korean barbecue grill, you need to consider the number of customers in the store and the amount of meals to buy. Therefore, Korean barbecue grills are generally larger than household ones. And also consider the hygiene issues during use. So should I use electricity, gas or carbon in Korean barbecue grills?
1. Korean barbecue grills use electricity, which is relatively safe, and the use process is relatively convenient, and the grilled food is clean. When using it, it will mistakenly think that the bottom plate of the machine is a baking tray and turn the machine on. Therefore, you should read the instruction manual before using the Korean barbecue to avoid damage to the machine.
2. Korean barbecue grills use gas, which can be smokeless when grilling, and the grilled food is clean. However, relative to electricity use, safety issues require users to pay attention to safety hazards such as gas leakage.
3. Korean barbecue grills use carbon, smoke will appear when grilling, and it is not very safe, but the grilled food tastes good.
Open flames are not allowed in large venues, so when choosing a Korean barbecue, you must choose a suitable Korean barbecue based on your actual needs.
