How to direct traffic to my restaurant website?

Well start small by putting it on a little things like this! I would've clicked on it had it been a part of this question, so keep that in mind. But to go bigger, I know there is a way to buy advertisements on Google so they show up on the side when you search or in that blue box at the top. My guess is that this is pretty costly considering that's one of the only ways Google makes money and it's a huge company, but it sure is worth a try!
