Decision. Anchor a tech-trip weekend on Voxxed Days Luxembourg, 18–19 June 2026 at Casino 2000 in Mondorf-les-Bains — it is the only major IT conference of 2026 that sits inside Moutfort village’s 10 km circle [8]. For a longer stay, Nexus Luxembourg, 10–11 June at LuxExpo The Box (~12 km away) is the flagship AI/tech summit [2], and hack.lu, 20–23 October at Parc Hotel Alvisse is the 20th-edition anchor for the cybersecurity crowd [4].
Ma Langue Sourit sits at 1 rue de Remich, Moutfort, ~10 km southeast of Luxembourg City and adjacent to Findel airport [1]. A 30 km radius from there covers all of Luxembourg’s IT-event venues — LuxExpo The Box (Kirchberg), Chamber of Commerce (Kirchberg), Parc Hotel Alvisse (north city), Crystal Park (Cloche d’Or), Belval/Esch-sur-Alzette, and Mondorf-les-Bains. It does not quite reach Trier (~35 km), Arlon, Metz or Saarbrücken, so this list is essentially Luxembourg-domestic.

Cross-border edge: what falls just outside 30 km
Moutfort is ~10 km from Luxembourg City centre, but the 30 km circle ends roughly at the German and French borders. Trier (~35 km) is the nearest German tech-event hub but sits just outside the radius — its main 2026 activity is academic (CiE 2026, 27–31 Jul and MCU 2026, 27–29 Jul at Universität Trier) [26]. Arlon (BE) sits right on the radius edge. If you’re willing to push past 30 km, IT.CON Saarbrücken (~70 km, 29 Sept 2026) is the closest cross-border IT/cybersecurity option — but it needs a separate trip from any Moutfort dinner reservation [27].
Practical tips for pairing a conference with dinner at Ma Langue Sourit
- The restaurant is open Tuesday–Saturday and is closed Sun/Mon [1]. All the conferences above run on weekdays or weekday-into-Saturday — there is no Sunday-only conflict.
- Voxxed Days (Thu–Fri 18–19 Jun) is the cleanest pairing: a Saturday-night dinner at Ma Langue Sourit closes the trip without conflicting with the conference.
- Nexus (Wed–Thu 10–11 Jun) likewise leaves the Friday/Saturday open. Same for Luxembourg Internet Days (Tue–Wed 17–18 Nov).
- hack.lu (Tue–Fri 20–23 Oct) runs through Friday — book Saturday-night dinner in the same week, then fly out Sunday.
- Venues used are all <25-minute drive from Moutfort: LuxExpo (12 km), Casino 2000 (9 km), Parc Hotel Alvisse (12 km), Crystal Park (10 km), Belval (25 km).
