FoodMaps
This just-launched, constantly-updated G-mashup's an ingeniously simple way to track the onslaught of Twittering food trucks, arranging maps by neighborhood (Westside/Eastside/Mid-City/Valley) and meal (Lunch/Dinner), with all the relevant details (grub, hours, etc) -- taking all the fun out of the chase, which is nearly impossible since it featured Charlie Sheen and Flea.
