I couldn't have picked a better audio for this game myself.
Great originality! I like the ragdoll physics and it really makes you feel like a drunken waiter. I like the fact that the input food items sometimes change on you; it helps add to the chaos and 'out of control.'
I think the only thing I would really improve upon would be the camera angle, but I saw that you mentioned you ran out of time on that which I totally understand. I will also throw out the idea of perhaps experimenting with a minimap? Or at least something that shows you what orders the customers want next, instead of having to run into the dining room every time to find out. But overall, great job!
