Dining Etiquette
Dining in Montenegro has few rules other than to be social. The atmosphere is relaxed and casual and if you break every rule few people will get offended, but not talking and rushing out the door after the meal will get strange looks and is considered rude.
To make your hosts talk about your visit for months after your visit however, try to follow a couple rules. First, bring a bottle of wine for you host and take off your shoes before entering their house, or leave your shoes at the door immediately after entering. You'll most likely be served multiple courses beginning with a soup and salad. You should accept every offering, but take small portions since there will be plenty of food and you'll probably be offered second helpings. If you really don't want more food, it will be a challenge to convince your hosts that you've eaten enough since the Montenegrins don't take "no" very well when it comes to food.
If you're in a business dinner setting the rules are very similar, but it's important to avoid business conversations. You hosts may bring up business over a lunch, but rarely over dinner.
At sit down restaurants with a waiter or waitress, round up or tip about 10% of the bill.
