Potatoes, onions, and spices are added to the stew.
Traditionally,the bouillabaisse is served in two course. The first course includes the fish broth, served with garlic bread, and a mayonnaise. The second course, is the fish itself. It is served with white wine. The following link provides recommendation on where to find true Marseille bouillabaisse; http://www.marvellous-provence.com/gastronomy/food/bouillabaisse-of-marseille.
In 1932, Paul Ricard, introduced Pastis, an anise-flavored liquor, which soon became a favorite drink in France, and in particular in Marseille. Pastis was invented as a substitute for absinthe, which was banned from sale 17 years earlier, due to its supposed hallucinogenic effects caused by one of its ingredients, wormwood. Actually, absinthe does not cause hallucinations, but in order to achieve its clear green color, it is over-proofed, (60% alcohol), and as result of this high alcohol content, could have many adverse affects on an "imprudent" drinker.
Pastis, at 40-45% alcohol by volume, is also a strong drink, and is usually consumed, mixed with water. The frequent stereo-type of a Pastis drinker, is an older French man drinking Pastis while playing Petanque.
The name "pastis" comes from Occitan which means mash-up.
