Wait a few minutes for the food to cool down, don't blow on it

When the food is just served and still very hot, wait a few minutes for it to cool down before eating. Don't blow on the food, if it hasn't cooled down yet and you put it in your mouth, you'll get burned and your face will be full of expressions.

If you order a burger and fries at an intimate dinner, feel free to eat it with your hands, because it's your own dish. If fries are ordered for everyone to share, use a fork to take some onto your own plate, then eat.
Don't cut the whole steak into small pieces and eat it all at once

When eating beef, pork, and chicken steaks, cut them as you eat them, keeping your dish looking attractive and neat. Cut enough pieces to be able to put everything in your mouth immediately and not chew noisily.
How to use napkins in fancy restaurants

In restaurants, you often see a beautifully folded napkin, placed on the plate before the food is brought out. It is usually used to place on the lap, if you have lunch, spread it out completely, and when you have dinner, fold it in half. This is the general rule when dining in any fancy restaurant, serving according to international standards. When you leave the table to do something and will return to continue eating, place the napkin on the chair. A napkin placed on the table signals that you are finished eating and the waiter will clear everything away.
Limit the addition of spices

Additional spices, such as salt, pepper, vinegar, or Parmesan cheese, should only be added after you have tasted the dish to see if it is to your liking. In an informal meal, you can feel free to add whatever you want, but in a formal setting, or a special dining experience, adding more spices to the dish can be considered tactless.
Some chefs want diners to experience exactly what they want to convey through the dish and to taste the difference. They spent a lot of time creating the dish and are confident that its flavor is perfectly balanced and does not need any additional seasoning.
Use a napkin to dab lightly around your mouth, do not wipe

You should regularly use a napkin to wipe your mouth while eating, especially when stopping to drink water. This helps keep the rim of your glass clean and not look messy. However, do not swipe back and forth, but gently dab around your lips with the napkin, it will look more elegant and beautiful.
