what's the context? I d assume the conversation was held in a restaurant. In Korea, if you order a main dish, it is usually served with many kinds of different side dishes. So in this case you can say, "별게 다 나오네". which means wow there is a lot of different types of side dishes. I can't really translate it literally though :(

I read the phrase from the link you attached. They are talking about an e-cigarette that smells like bubble gum. And 'SteveJobs' is a bit surprised to see that now we can vape bubble gum-tasted e-cigarettes. He seems to be not interested in that, by saying '별게 다 나오네요'. That's why Siyang said we use the expression whenever there is something useless. When new technologies and exotic dishes that are not necessarily helpful to you but surprises you anyway, you can use that expression.

It means you said something useless/meaningless . It's better if you tell me the whole conversation
