Choose the perfect room for your 21-diner

Every 21-diner has a different vibe. Whether you’re hosting a candlelit supper with a few loved ones or a festive dinner with speeches and a dancefloor, there’s a room to match.

Intimate and elegant

• Terraszaal (30 m², 2–14 guests): Ideal for a small, curated guest list and a quietly luxurious dinner.

Mid-sized gatherings

• IJsselzaal (75 m², 10–60 guests): Great for a seated dinner with short speeches and a slideshow.
• Hoogstraatzaal (75 m², 2–80 guests): Versatile for medium-sized dinners that may grow into a post-dinner toast.
• Tuinzaal (75 m², 2–135 guests): Flexible capacity for dining plus space for a dessert course with toasts.

Large and lively

• Commanderijezaal (100 m², up to 120 guests): The largest indoor room for a full 21-diner program: welcome, seated courses, and a festive finale.
• De Commanderije van Sint Jan (120 m², 2–120 guests): A restored former chapel one minute’s walk away—rich in history and ambience, perfect as a plenary dining hall or as a breakout for reception versus dinner.

Outdoor touches—cleverly used

• Rooftop terrace and rustic garden terrace: Lovely for a welcome drink or photos. The rustic terrace is heated for comfort in cooler months. Background music is permitted outside.
• Important: Full-scale parties are indoors (allowed until 01:30). Use outdoor areas for arrivals, mingling, or a brief intermezzo—then move inside for the main celebration.

Comforts that matter

• AV-ready: A basic AV set, microphones, and fibre‑optic internet help you run videos, slideshows, or live speeches smoothly; a technical expert can be present.
• Wheelchair accessible spaces ensure everyone is included.

Craft a menu that tells your story

Food is the heart of a 21-diner. The on-site French–Dutch restaurant focuses on local, seasonal produce at a gastronomic level, and the kitchen reliably handles allergies and dietary requirements.

• Private dining, perfectly paced: The team coordinates the cadence of courses with speeches, slideshows, or a surprise toast, so your story flows.
• Vegetarian and vegan options: Thoughtful alternatives that feel as celebratory as the main menu.
• Themed concepts (optional): If you want to dial up the personality of your reception or after-dinner moment, consider High Tea, Tapas, live Wok stations, an Oyster & Caviar bar, Sushi, Wine & Food pairings, traditional Dutch games, Casino night, or even a Murder-Mystery dinner twist.

Wine, pairings, and after-dinner signatures

• Wine arrangement: Half-glass pairings are available at €6.50 per glass or €12.00 for two glasses.
• After-dinner favourites: Elevate the finale with liqueur coffees and sweets:
  • Irish coffee, French coffee, Spanish coffee, Italian coffee, Calypso coffee, and Dom coffee — €9.75 each
  • Bradley’s tea (organic, various flavours) — €3.50
  • Fresh mint or ginger tea — €3.95
  • Bonbons (4 pieces) — €6,50

Tip: Plan your toasts just before dessert, then segue into after-dinner coffees and bonbons for a smooth, celebratory close—or to transition into music.

Personal touches and entertainment

A 21-diner shines when it reflects the guest of honour.

• Music & entertainment: Both live bands and DJs are welcome indoors. The events team can source and coordinate performers to your budget.
• Games & themes: Bring personality with traditional Dutch games, a Casino table, or a theatrical Murder-Mystery layer if that suits your group.
• Speeches that land: Use the microphones and AV to keep remarks crisp. Fibre‑optic connectivity helps with remote tributes or surprise video messages.
• Photo opportunities: The historic interiors and partner locations offer characterful backdrops; you can welcome guests on the rooftop terrace or rustic garden terrace before dinner.
