Where do you go when you're dying of thirst and don't want to spend a fortune? McDonalds. Dollar menu for sodas rocks. They're usually pretty quick through the drive-through, although sometimes you get people who don't seem to understand what soda water is. But the fact that McDonald's even has soda water, makes me really happy. If you're know the mood to splurge, a vanilla shake and fries hit the spot. I also love their sweet BBQ burger!
