No, it is not bad etiquette to skip ordering a drink before your meal at a restaurant. Ordering drinks is a matter of personal preference, and people have different reasons for choosing to have or not have a beverage before their meal.
While some individuals enjoy having a drink as part of their dining experience, others may prefer to focus on the food or simply not have a preference for drinks with their meal. Some people may also choose not to order a drink for health or personal reasons.
Good restaurants and their staff understand and respect individual preferences when it comes to ordering. As long as you are polite and respectful to the staff and other guests, it is entirely acceptable to skip ordering a drink and proceed with your meal.
If you change your mind later or decide during the meal that you'd like a drink, you can always order one at that time. The key is to be considerate and not feel pressured to order something you don't want just because you think it's expected.
Ultimately, dining out is about enjoying good food and having a pleasant experience, and the choice to order or not order a drink is entirely up to you.
