A bit dark, and you can't really see the ceiling, it's just a black shape dominating the photo. You could crop it down by half, and straighten out the photo at the ceiling line (it's tilting down to the left), and strengthen this considerably.

True, it was tilting, MossyB, so I did try to get it upright. Too dark also, though nothing I could do in this area. Fiddling with the "Brightness" slider was turning all the white parts in the photo overexposed. This one I shot stealthily through an open window, as I was walking by.

what an interesting looking place.

I think I'd feel like I was in a bird cage

This photo is more about a street corner than a restaurant.

i guess, but also everything in the picture is part of the restaurant too, so.........

I'd crop off the second floor of the building and the foreground up to near the feet of the frontmost chair.

Thank you guys for your advise, I'll try to do what I can with this shot and in future will pay attention to the composition
