Not sure if we even have a Chinese store around here, assuming that is where one has to go to buy some of that.

Any decent online shop that you are familiar with that sells it?

You can buy it at Sprouts, Whole Food and Nature store.
Or, you can buy them at Amazon and Ebay, they're called Goji berries.

Oh good, thanks!

Are those edible without cooking them or best eaten when cooked?

Best eaten straight from the bag!
Or you can sprinkle them in a Salad or on your morning cereal or oat-meal, mix in scrambled egg.

I like to boil them in water as a tea.
