I'm not sure if this makes sense, but I would possibly choose different photos depending on where they are at in the restaurant. If they are over the tables, where customers would be looking at them while eating, I might choose the more "relaxing" images, whereas if they are all in an entryway I might choose more that have a bit more "oomph" like the ones with the bull bellowing.

Overall I like best 2, 3, 5, 6, 7, 12, and 14. I especially like 3 and 12.
