Spouses may be included in business dinners. Female guest of honor is seated to the right of the host. Male guest of honor is seated to left of the hostess. Dinner is often served immediately at dinner parties. There may be no cocktail hour.
Toasting is something of a formal ritual in Sweden.
Don't take a drink until your host has given a toast. Allow hosts and seniors in rank and age to toast first. When toasting, make eye contact and nod to the others present, before putting your glass down. After making a toast, the men wait for the women to put their glasses down first. Do this immediately.
