Restaurant in Ixelles, Belgium
Two Michelin Plates. Book it without stress.
Quartz holds back-to-back Michelin Plate recognition (2024 and 2025) and a 5-star average across 92 Google reviews — an unusually consistent track record for a €€€ modern cuisine restaurant in Ixelles. It is not the easiest booking in the neighbourhood, but it is one of the most reliable. If you have been once and are weighing a return, the answer is yes.
The number that matters most here is 92: Quartz holds 92 Google reviews averaging a perfect 5 stars, a signal that repeat visitors are not just satisfied but motivated enough to say so. Pair that with back-to-back Michelin Plate recognition in 2024 and 2025, and you have a modern cuisine restaurant at the €€€ price point that is consistently delivering on its promise in one of Brussels' most food-literate neighbourhoods. If you have eaten here once and are deciding whether to return, the answer is yes.
Ixelles is not a neighbourhood that forgives mediocrity. The stretch around Rue de la Réforme sits within walking distance of the Flagey square, a hub that draws a cosmopolitan crowd with high expectations and plenty of alternatives. Quartz at Rue de la Réforme 22 has positioned itself as a reliable anchor in that environment rather than a destination that depends on novelty or hype to fill seats. The Michelin Plate, awarded in both 2024 and 2025, confirms consistent kitchen execution — it is Michelin's signal that a restaurant delivers cooking of a notably good standard, not a one-season wonder. For a neighbourhood local deciding where to take a guest who visits from abroad, or for a regular trying to decide whether Quartz warrants a place in the monthly rotation, that consistency is the core argument.
Modern cuisine at this price tier in Ixelles tends to split in two directions: either it reaches toward tasting-menu formality with ambitious technique that can feel effortful, or it settles into a comfortable bistro register that underdelivers on ambition. Quartz sits closer to the first camp , this is a restaurant with clear culinary intent, not a neighbourhood fallback. The €€€ pricing puts it at the same tier as Kamo and Amen, which means you are choosing between distinct experiences rather than comparing value equivalents. The Michelin Plate tips the balance toward Quartz if your priority is classical kitchen craft over concept.
For the regular visitor, the question is less about whether Quartz is worth a first visit and more about how it fits into a broader Ixelles rotation. Given the cooking register, Quartz works leading for a dinner where the food is the point , not a quick catch-up over plates, but a meal you are arriving to eat rather than simply to socialise through. If you have been once and found the experience measured rather than warm, that is not a flaw in the restaurant; it is a calibration cue. Return when you want precision. On nights when the priority is a looser atmosphere, Amore, Pasta e Gioia or Car Bon serve different needs at lower price points.
With 92 reviews and a perfect score, Quartz clearly has a loyal following, but this is not a table that requires three weeks of planning. Booking difficulty is easy, which is part of the appeal for a neighbourhood anchor , you can plan a week out without anxiety. Reservations: recommended, particularly for weekend evenings, but not difficult to secure. Dress: not confirmed in available data, but a €€€ Michelin Plate restaurant in Ixelles typically expects smart casual. Budget: €€€, consistent with comparable modern cuisine at this level in Brussels. No phone or website is currently listed in Pearl's database, so booking via a third-party reservation platform is the practical approach.

Belgium's modern cuisine tier is credentialled at the leading end by restaurants like Hof van Cleve in Kruishoutem, Boury in Roeselare, Zilte in Antwerp, Willem Hiele in Oudenburg, and Bartholomeus in Heist. Quartz is not competing at that starred level, but that is not a criticism. A Michelin Plate in Ixelles, sustained across two consecutive years, is a meaningful credential for a neighbourhood restaurant operating at €€€. It signals that Michelin's inspectors found the cooking worth noting , not once, but twice. In a city-district where the dining options are dense and the competition is real, that is a durable trust signal. For international context, the kind of precise modern cooking Quartz represents finds its clearest expression at the leading of the format in restaurants like Frantzén in Stockholm or FZN by Björn Frantzén in Dubai , Quartz is operating well below that altitude, but the culinary register is recognisably in the same tradition of ingredient-led, technically considered cooking. And at the Brussels neighbourhood level, Bozar Restaurant represents a comparable institutional modern cuisine option if you want a grander setting for a similar budget.
If you ate at Quartz once and came away with a sense that the kitchen had more to show than one visit revealed, trust that instinct. The consistency of the Google rating across 92 reviews and the repeated Michelin Plate recognition both point toward a restaurant that is not coasting. For the regular who wants to deepen familiarity with one of Ixelles' most dependable modern kitchens, a second visit is the right call. Go with the cooking as your focus, not as background to a long evening of conversation, and Quartz will likely confirm why it keeps its ratings where they are.
