Fine dining etiquette at a restaurant is a little bit different in some very specific areas from etiquette at a private dinner party at someone’s home. For the most part, however, much of the same rules apply in both situations. Basic table manners, such as sitting up straight, keeping elbows off the table and chewing with a closed mouth are imperative. Proper napkin and utensil use is also an important part of fine dining etiquette. A person’s clothing choice should be carefully considered as well.
When people dine in a casual environment, attire is much less important than it is at an elegant meal. In a relaxed atmosphere, t-shirts, jeans, shorts or sneakers might be appropriate. In general, that type of clothing is not considered proper fine dining etiquette.
