IMHO, the Denon AVR-X3600H is not the appropriate choice for such a setup. For music you probably only need a stereo source and maybe a speaker selector.
What's the music source, btw?
Some examples of speaker selectors are shown here.
An article about how/why to use them
Some allow you to control the volume each pair of speakers around the restaurant, others are simple on/off buttons per pair.
In theory you could try to drive all 8 speakers from one stereo receiver (if speakers are connected in series!
), but it may be hard to get the volume levels right in each area of the restaurant.
You may also consider making the music mono audio instead of stereo so placement of right/left speakers doesn't matter.
Some stereo receiver examples from best buy include Insignia NS-STR514 (it looks like this is made by Sony), Sony STR-DH190, Yamaha R-S202
They should have enough power to drive all the speakers, and A/B speaker selection for 4 speaker terminals in case you did want to try to run them all from the one box. If it seems like too much for one, they're cheap enough to just buy another.
I'd test the speakers before trying a sub, and even replacing the speakers with ones capable of playing lower. Getting even subwoofer response all over the restaurant might present a challenge.
Amazon and Monoprice are places to look for wall mounts for the speakers. Make sure that they support the weight and dimensions of the speakers you have. If the windows take up _all_ of the exterior walls, and you don't want the speakers facing down, some kind of L-shaped bar could be mounted to the ceiling to provide a mounting point, or you could mount on interior walls facing the exterior walls/windows.
BTW, if it's too late to return the Denon, I'd be happy to swap my proposed solution for it and take it off your hands

Before we used to hang speakers of the concrete ceiling, now I don't know what's best. Probably need at least one sub? Can someone help on setting up? The restaurant is basically L shaped with large windows from ceiling to bottom all around and tables by these windows..
