What Restaurant Schlüsselzunft does

Zunft zum Schlüssel guild and first documented in 1306. The venue offers à la carte fine dining in the historic Zunftstube (with a swan tiled stove centerpiece), a Parisian-style Bar & Bistro with a boulevard terrace on Freie Strasse, and two banquet rooms — the Zunftsaal for 40–130 guests and the Vorgesetztenstube for 12–30 — supported by a kitchen led by Executive Chef and co-owner Andreas Uebersax. Revenue streams include business lunch (CHF 55–69), à la carte fine dining, classic bistro, afternoon tea (CHF 39–55), seasonal Fondue Chinoise (October–April, CHF 52–79), Christmas and New Year's Eve set menus, MasterChef Schweiz dinner events (CHF 165/person), and gift vouchers; banquets and events are managed by Sascha Brestler and Jana Rieder via direct sales. The restaurant is the official club locale for three Rotary Clubs and the Basel Investor's Club, holds memberships in Gilde etablierter Schweizer Gastronomen and Chaîne des Rôtisseurs, and received the 2009 ICOMOS Switzerland Special Prize for Historical Hotel/Restaurant of the Year. The site is operated by Solbad Gastronomie AG, co-owned by Sascha Brestler, Andreas Uebersax, and Roger Lehmann, which also runs Gasthof Solbad (since 2001), Sommerpark am Rhein (since 2003), and Schloss Schadau in Thun (since 2019).
