For a supposedly cosmopolitan city, San Francisco has relatively few (read almost zero) eateries that deliver their own food. Using such services as Waiters on Wheels adds time and money to the equation. But the local outpost of 'wichcraft, the sandwich emporium of telegenic and award-winning chef Tom Colicchio, does deliver — possibly because the parent company is located in New York, where you can get everything delivered 24/7. And delivery is free, within a downtown area bounded by Fifth and Second and Post and Folsom (with a teeny minimum of $4); $10 gets added outside those boundaries (within an indeterminate area, negotiable depending on the size of the order). Delivery starts at 11 a.m. and ends at 4 p.m.: You could order from your office desk and conceivably try onion frittata with roasted tomatoes and cheddar on ciabatta for elevenses, Sicilian tuna with fennel, black olives, aioli, and lemon on a baguette for a late lunch, and tote home roasted pork with coppa, pickled pepper relish, and fontina on grilled country bread for dinner in front of the tube.
