Finding a decent keto lunch in central Brussels, the area around the Royal Palace, the Coudenberg, the Mont des Arts, is harder than it should be. The default is sandwiches, and the sandwich shops in that neighbourhood cater to the office lunch crowd with baguettes and wraps and very little else. SuperBowl on Coudenberg is the exception worth knowing about.
The format is a composed salad bar: you pick a base, choose your proteins and toppings, pick a dressing. Everything is assembled in front of you. For keto purposes this is ideal: you can build a bowl that’s almost entirely protein, vegetables, and fat, skip anything starchy, and actually know what’s in what you’re eating.

What to get
Skip the grain bases (quinoa, rice, and similar) and go with the leafy green base or whatever the lowest-carb option is on the day. The protein options usually include chicken, tuna, egg, and various others depending on what’s available. Load up on protein, add whatever vegetables look good, and choose a dressing carefully: vinaigrette or olive oil is the safe option, the creamy dressings vary.
The avocado, when they have it, is worth adding. Seeds and nuts as toppings are fine in reasonable quantities. Croutons are not for you.
The portions are generous enough that it’s a proper lunch rather than something you’ll need to supplement with an afternoon snack.
The location
Coudenberg 68, a short walk from the Royal Palace and the Palais des Beaux-Arts. The neighbourhood is mostly civil servants, EU-adjacent office workers, and people visiting the museums on the Mont des Arts. It gets busy at lunchtime and the queuing system moves reasonably quickly.
The price point, €10-20 depending on what you add, is fair for central Brussels and for a lunch you’ve actually composed yourself rather than a sandwich from behind a glass counter.
In context
Most of the eating options in that part of Brussels are either sandwich shops, expensive brasseries, or tourist-facing restaurants near the Grand-Place. If you’re working nearby and eating lunch out regularly, the composed salad bar format is one of the more sustainable keto-friendly options you’ll find without going significantly out of your way.
It’s not a destination restaurant. It’s a reliable lunch spot that solves a specific problem, eating well on keto in a part of the city that doesn’t make it easy, and does it consistently enough to be worth knowing about.
