It won't sound right....
You should use commercial gear for that, 70vlt system.
Try Symetrix Jupiter, Lab Grupen, Shure wireless mics, LG commercial LEDs, Solstice 4K Pod and Atlona CLSO presentation switch with mirrored outputs. Try sound tube or tannoy 70vlt speakers, even Bose DS.
Then use your control system of choice.

This would give them the ability to have live sound, media from devices such as laptops, phones, and tablets.
Probably would cost $20,000 or so.

If you wanted to get crazy, add a few PTZ robotic cameras from Vaddio or Snap to display on the TVs what is cooking at the kitchen area.
