Tucked away in an inner courtyard is Franz (the name is derived from the female-forward concept of "Frauen im Zentrum"), a space dedicated to culture, work and food. The latter is to be had here at Wirtschaft im Franz, in the form of a cleverly devised surprise menu comprising four, five or six courses. Modern and seasonal dishes such as "Beetroot, leek, mustard seed, horseradish" are pleasingly pared back and creative without being fussy. The emphasis is on the quality of the produce, with vegetables taking centre stage. Information on the ingredients used and their sources is listed on the menu, and the front-of-house team is happy to provide further details. The feel of the place is also lovely: the open kitchen and trendy bistro style make for a pleasingly unpretentious, friendly and urban atmosphere. Gorgeous inner courtyard terrace.
