How to make a German industrial Italian restaurant?

The landlord's question is quite difficult. Italy is a southern European style, Germany is a Western European style, Italy is brighter and Germany is darker. If I want to design it this way, my plan is to design the floor as a light gray monochrome carpet or tile, and the wall surface should be a light gray monochrome wall (try to use plastic board as a decorative surface), which should be flattened and frosted to make the light on the wall diffuse and soft.

In addition, the corners of the interior pillars are made in a stiff straight line style, and there are no curves as much as possible. The ceiling can be used in a cool medium depth or lighter color, the key is to use a mixture of cold and warm colors for the lighting (more cold colors, warm colors for the key parts of the lighting), and the lampshade should be frosted lampshade. The edges of the dining table are decorated with polished metal plates, the center is made of thick glass, and the floor of the guest seats is made of dark earthy yellow wood floors.

It's hard to say about eating in a factory, but I don't know if anyone is willing to do it with culture, not with hardware.
