On bad coffee

Coffee in Japan is easy to come by. They love the stuff here. Well... mostly ice coffee. The problem, is that this coffee is american-grade weak, whereas I'm more of an espresso guy. So while the cans of ice coffee you find in vending machines (conveniently located every 10 meters, anywhere and everywhere in Tokyo) are cheap, at ¥120 (about a 0.80€, or 0.50£), I need a few during the day to get my dose. It's also hard to guess what you're getting based on the label... apparently, based on how "European bitter blend" tastes, europeans like their coffee week, milky, and super-sweet (they must be thinking of the british...); "quality roast" basically means "sh*t"; and "deluxe espresso" means "sugarwater + eau de brown crayon"...
