First part of the question: solved by US-based Red Bubbler PBWright, who answered that it is rippling water.
Second part of the question: In which city did I shoot this image? Solved by “PBWright” once again, answering correctly that it was shot in Melbourne. This is the surface of the Yarra River, as I spotted these reflections late on Friday night. This was shot without a tripod, using a 70-300mm lens.
I do not crop, enhance or post-edit my images in any way. Shot with a Pentax K100D, using a Sigma 70-300mm lens. F5.6, 0.5 sec, ISO 800, focal length 300mm.
