There's a really fascinating article on Slate.com this morning about how to get a better cup of coffee from Starbucks. Essentially it tells you how to order a "shorter," better cappuccino, even though it's not on the menu.
Honestly? I don't think this will have much impact, since most of the people I know either order ginormous coffees on principle or get them with flavoring and whipped cream. Reality in my 'hood is that tiny, tasty coffee doesn't have the appeal of a huge bucket of sugar. I'm going to try a short cappuccino though, because I have never really believed that value is measured solely in quantity.
