The city hall and music theatre complex was completed in 1988 following the demolition of the last of the city's old Jewish quarter. If you have to do city council things, this is where you will come. But for most official business, like driving licences and print-outs from the population registry, its probably quicker to use your borough council offices.
The theatre was nicknamed Stopera (stop the opera) and now cheerfully uses it. Home to the national ballet, opera and symphony orchestra.
Café Danzig is not a bad spot for a pre prandial.
