What kind of butter do restaurants like olive garden use for their pasta?

I am trying to make pasta at home that tastes like Olive Garden pasta (which I have with butter instead of alfredo). I believe that the reason that my pasta doesn't taste the same is because of the butter I use. I use Land of Lakes salted butter and I noticed that when I add the butter to the pasta the butter isn't very visible vs. when Olive Garden uses butter it becomes a darker yellow liquid that ends up tasting much better. What brands of butter do restaurants like Olive garden use? Or is there something special they do to the butter to make it taste better (I just add 5 tablespoons of the butter to a pound of pasta after I take it out of the strainer and then I mix the pasta).

What you are describing is probably browned butter. It's not the butter they use but the technique as any butter will do. Pasta is usually cooked with its sauce before putting it on the plate, you can re-create this very simply.

First get a pan big enough to toss your pasta in, then get it on a high heat and add your butter. Melt it, then cook it until it takes on a slightly brown tint and smells a bit like nuts, then get your cooked pasta in and toss it or stir it around to coat. A small scoop of the pasta water will keep it from drying out and give it a nice sheen as well.
