Despite her culinary prowess, San Francisco's delivery culture is sadly lacking, with few resources outside of the menus elusive deliverymen rubberband to your doorknob. Expand your hunger's horizons with Grubhub.
Already huge in Chicago, Grub's aiming to list every SF delivery option, from Araujos Taqueria to Big Nate's BBQ (founded by 6'-11" Warrior great Nate Thurmond, who deserves a huge tip for folding himself into that tiny delivery car).
Search by map or punch in your zip, and up'll pop every area spot willing to facilitate your unspeakable Mind of Mencia marathon, plus hours/menus/archiving capability. Unlike MenuPages, Grub also posts coupons (free Crab Rangoon!) and online order forms customizable down to the pizza topping -- you can even leave special instructions, like "extra salty", or "Nate, please autograph my Memphis Pork?"
Of course, there're the obligatory user reviews, but these mostly eschew foodie-speak for bluntness, e.g., "Good food. Guy showed up", or "I wouldn't feed this to my worst enemy. Well, maybe I would..." -- a thinly veiled reference to that ghostly deliveryman even now scampering away away from your door.
