Julia Fish & Oysterbar – Seafood in Koksijde, Belgium

Julia Fish & Oysterbar in Koksijde

At Julia Fish & Oysterbar, the sea sets the rhythm. Located in Sint-Idesbald, this is a place where the day’s catch dictates the menu. The restaurant is paired with Mare Nostrum, its own fish shop selling fresh fish and delicatessen—a seamless connection from ocean to plate.

The kitchen focuses on seafood, served in a style that encourages sharing. Begin with an Oyster Academy (six oysters) or Fishermen’s Delight for at least two. A la carte options include Bruschetta Julia with rouget and sweet chilli, and Oester Belle Isle n°3 with ponzu and pickled chili.

Sharing dishes are the heart of the menu. Look for smoked salmon with horseradish and sour cream, North Sea crab with cauliflower and beurre noisette vinaigrette, or tuna tartare with wild garlic pesto and pommes pailles. Hand-peeled shrimp with white asparagus and poached egg, and crispy rouget with tomato chutney and coriander seed are other highlights. Scottish langoustines and Breton lobster are served simply with beurre noisette or herb butter.

For mains, there is cod with white asparagus and mousseline, skate wing Grenobloise, and steamed sea bass with beurre monté and caviar. A Catch of the Day is always available, priced by the day.

Julia’s house rules keep things simple: a choice of up to three main courses per table. Lunch is served for the full table only. Last call is 23:30 on Friday and Saturday, 22:30 other days, and 15:30 for lunch.

This straightforward, ingredient-led approach earned Julia Fish & Oysterbar a Michelin recommendation in 2026. Counter dining and outdoor seating are available, making it a welcoming stop on the Belgian coast for anyone serious about seafood.
