The transitory nature of food trucks can make them tough to take advantage of, which's only compounded by the fact that most are too busy making sandwiches to fall victim to your Three-card Monty anyway. Track 'em down easier than that duplicitous queen, with MSP Street Food.
A keen aggregator looking to bring order to the oft-chaotic TC mobile munchies scene, Street Food tracks and displays roving restos' locations, changing menus, and payment options, and even links to reviews from local food bloggers, aka the only people with the time to track down locations, menus, and payment options on food trucks. Because finding good street food requires finding good street food, the crux of the site's a 24-truck/cart (and growing) vendor list attached to a Gmap that's updated directly by SF's peeps and the trucks themselves, whose locational insights can be supplemented by links to each one's tweets on a live feed, which'll in turn allow you to do the same. Should you want a more free-form journey through their vast cull, you can filter by price, diet type (gluten-free, vegan, or vegetarian), cuisine (including styles like "Mexican-Asian fusion", or more simply "tacos"), and payment method, all helping you sort vendors like Potter's Pasties, Fork in The Road, and The Waffle Van, which is also a sequel where Ryan Reynolds takes a closer look at Tara Reid and rethinks the whole thing.
Should pure unadulterated convenience be your thing, they've also got a map tool that'll geo-locate you and drop numbered pins to mark every truck nearby -- a departure from your standard scam, where you are making those sucker-ass trucks the mark.
