After a few views of this image, here is my "take" on it.
First and foremost Wolfgang has captured a very good light here.
The composition is solid, and IMO the main subject is the MARTINI sign, but instinctively the first thing I look at are the people and what they are doing, here are 3 areas of interest, the seated woman, the suave suited guy and the waiter. The backpacker holds no real interest.
After taking in the "people action", I am then drawn to the architecture, and the repetition of the arches, this sends me deeper into the image, finally I am pulled back by the MARTINI sign and that holds my final attention. I liked the journey through this image.
There is a subtle secondary reinforcing of the title in the Top RH corner of the image with a second inverted sign. This is quite playful, and made me search for more.
I guess that Wolfgang is either a tall man, or he held the camera above his head for this shot, as the focal plane is pointing downwards, this has caused the verticals to converge opposite to the norm (eg. the arch columns appear further apart at the top than bottom) this is a little distracting, but not overly so.
All in all a good image, with lots going on (in a GOOD way)

.
Nice one Wolfgang!
