I bought a cheep small dining table for the kitchen when I moved in here, and it's OK and all, but I would like to make the wood more natural looking and possible a bit darker. Right now it looks almost like this, but not as shiny and not quite as yellow (which I think is because of age, it probably looked like that first):

I'm not sure what this type of finish is called in English, lacquer?
So, what is your best advice for getting it off? Sand paper? I don't have any fancy equipment but could maybe borrow if needed. And then what do I do with it? I guess I need some kind of treatment on it?
