Outdoor Kitchen and garage faucet plumbing

Hi,
I am building an outdoor kitchen and garage at the same time, I plan to install a sink in the outdoor kitchen and a outdoor faucet for the garage. I have the trench dug and city inspector approved already.
My question is what type of pipe tubing should I run for the sink and faucet. A Home Depot guy recommended PEX - which I don't believe can be buried. I have been told not to use PVC due to the connections, but to use tubing. A master plumber at another Home depot recommended CPVC and that Poly tubing is not allowed for potable water. I don't plan on drinking the water in the sink or faucet but you never know. I read many blogs and sites and everyone has an opinion all of them different, I can't find it in the code. Any ideas.
Just a couple more pieces of info, I don't want need hot water, it will be buried in the garden, not under a driveway or slab, the trench is 24 to 18inch deep, frost line is 24inches, and I plan to blow out the water every winter season and I am based in Virginia.
Many thanks

160 psi poly is the ticket !
Here in Idaho 99.9 % of new homes use poly from the meter to the house.

That is a joke.

I agree with the other poster, poly is the way to go. Poly is most certainly approved for potable water. PVC in 20 foot lengths with bell ends is another reasonable choice.

Even though you say you plan to blow it out for the winter, the inspector may require you to bury below the frost line. And he is doing you a favor by doing so.
