Not much competition here. San Francisco is a bad sandwich town, so any place that doesn't charge $10 for two slices of Wonder bread and some gristle probably rates a mention. Even so, King Foot, a tiny sub shop in the Lower Haight, is great by any measure. The subs come hot or cold, 6-inch or foot-long, with tuna, meatball, salami, roast beef, and so on. The toppings are fresh; the lettuce isn't that awful Subway confetti that's usually dumped on grinders like these. Everything's a bit pricey, by sub standards -- about $4 for a 6-inch, $7 for a foot-long -- but if that's what it takes to get a good sandwich around here, we're willing to pay.
