I don't have much night shooting experience but you are getting better for sure. I don't like the composition at all personally. If you like the raised portion of the corner of the building you should find an angle the features it most prominently. I would go after closing when there are no cars, hopefully they leave these lights on. Maybe go when its very slow, it looks popular, they must have good food
I think the parking lot light and tree kind of ruin the view of the corner of the building. I also am distracted by the overhead utility lines. The angle I like is from under that billboard, however I suspect that there not windows on that side of that roof structure. There is so much going on in front of the what you want to emphasize, I would try to eliminate some of them now that you have solved some of the technical aspects. Maybe a closer oblique low angle with building and more sky. I think the color in the sky is very nice but hidden.

Does that tree ever go bare? Winter may be better.
