The indifferent staff may take a while to get it to your plate, but once you bite into this oven-baked combination of crisp green-onion foccacia, tender meatballs, rich sauce, soft red onion, and melty Swiss cheese, all will be forgiven. Throw in an Anchor Steam for the full effect.

Grab your preferred roll from the bin (we like it on toasted Liguria Bakery foccacia for an extra $1) and let the friendly Italian crew whip you up this combo of tender prosciutto and coppa with fresh, creamy mozzarella and sweet sun-dried tomatoes.

What can be said about Roli Roti's porchetta that hasn't already been said? You will wait in line for it. A long line. You will smile at the sandwich-maker and be given a chunk of astoundingly glazed skin, as crisp as caramelized sugar. You'll watch as your sandwich is mopped in juice and piled high with tender meat and crunchy arugula and more of that skin. And then you'll be carried away on a cloud of porky deliciousness.

A trio of meats (corned beef, pastrami, and brisket) is the cornerstone of Deli Board's most iconic sandwich, which is definitely not for the faint of heart (or those who forgot to refill their Lipitor). Topped with Muenster cheese and brown mustard, it's supreme hangover fare.

Lunchtime crowds flock to Dennis Leary's sandwich stand for fresh-baked foccacia packed with tender corned beef, creamy Russian dressing, and plenty of shredded cabbage. A housemade pickle and a signature Andes mint for afterwards complete the tableau.

Ike's menu is as long as a Pynchon novel and about as full of wacky names, but this sandwich is the budding empire-builder's perennial best seller: chicken breast, BBQ sauce, honey, cheese, and the signature Dirty Sauce, a garlic aioli.

We have Pittsburgh to thank for the outstanding all-in-one sandwiches served at these Mission and North Beach twins, which are stuffed with provolone, slaw, and the linchpin, fries. A runny-yolked fried egg completes the tasty melange of hot, creamy, vinegary goodness. Grab a beer and root for whatever Pennsylvania sports team is at it this week.

This unassuming corner deli blossomed a few years back into a sandwich magnet for Valencia types, and now you'll always find hungry folks waiting for lunch on the benches outside. They're here for a variety of items, but the Korean steak sandwich, with chili and garlic-marinated ribeye, house pickled onions and jalapenos, and plenty of cheese, is the perennial favorite. (In a just world, this spot would be held by the late, lamented pork katsu sandwich, which we're still missing two years after it disappeared from Rhea's menu.)

There's no need to sell anyone on a great cheesesteak, so we'll keep it simple: this is SF's best iteration and they sell Tastykakes, too. All you need to know, really.

The numerous creative sandwiches on offer at Pal's Takeaway make it hard to pick just one, but the perennial favorite is the Lao sausage banh mi, with spicy, lemongrass-infused sausage topped with sweet pickled carrots and bitter greens. It's not always available, so check their Twitter before you visit.

All the tortas here are great, but it's the pierna enchilada, a mound of pulled pork topped with plenty of beans, avocado, and jalapenos and stuffed inside a crisp-soft torta roll, that makes this 24th St. joint an icon. No need to order big, by the way: the mini version is more than enough for most eaters, and full-size is best for hangovers or leftovers.

Each day, the lines extend out the door for the one and only sandwich Bakesale Betty makes: a cold duo of fried chicken and jalapeno-studded, crunchy-spicy slaw on a torpedo roll. It's enormous, delicious, and delivered by a crackling-fast staff that probably continues making these things in their dreams. The gigantic cookies are great for dessert.
