Migros Gourmet in Bahnhof SBB, the Swiss train station, a store of the largest grocery store chain in Switzerland, provides sandwiches, tarts, fresh-baked bread, pizza, döner kebab, etc. at very reasonable prices, perfect for picnic lunches on outings. Similar: the Coop shop opposite the station (Centralbahnstrasse). Unlike all other grocery stores in the city, both are open late at night and on Sundays.
