Food carts are the most trendy thing right now, next to bacon, sourcing food locally and thick nerd glasses.  This is a food cart in Portland, OR - I know, I know, I don't live there, hell, I've never even set foot in the state (not because I don't want to, but because my travels have never taken me there).  But I saw this on the Cooking Channels' 'Eat St.' and it looked really good and greasy - greasy in a wonderfully fulfilling way.
If I ever get to Portland, I want to visit this mecca and pay homage to the Food Gods of Goodness.

I especially like the 'Redonkadonk Burger' and the 5-oh!
Yum!
