Potbelly Secret Menu Guide 2026
Here’s the short version: the Potbelly secret menu is real, and it goes by the name Underground Menu. It lives inside the Potbelly app, where you’ll find mashups like the Lucky 7, the Wrecking Ball and the Sicilian. You can also order these in-store by name or by spelling out the customizations.
I’ll be honest, when someone first told me Potbelly had a secret menu, I figured it was one of those internet myths that never quite pans out. But this one’s different. Potbelly actually built it into their own app. No winks, no code words needed. You just have to know where to look. And if you’re more of a walk-up-and-order person, don’t worry, I looked into that too.

What Is on the Potbelly Secret Menu?
The Potbelly secret menu, officially called the Underground Menu, is a lineup of about nine off-menu mashups that combine ingredients from regular sandwiches into new builds. Think of them as fan creations that got popular enough for Potbelly to feature them in the app. Here’s every one I could verify, plus exactly how to get each.
| Sandwich | What It Is | How to Order |
|---|---|---|
| Lucky 7 | A Wreck (ham, turkey, roast beef, salami) combined with an Italian (salami, pepperoni, capicola, mortadella) with provolone. The meat-lover’s jackpot. | Say “Lucky 7” in the app or in-store |
| Wrecking Ball | A Wreck loaded with meatballs, Swiss cheese, mayo, lettuce and tomato. | Say “Wrecking Ball” or describe the build |
| Fireball | Meatballs with cheddar, chili and hot peppers. Bring a drink. | Say “Fireball” by name |
| Cheeseburger | Meatballs, cheddar, mayo, mustard, lettuce, tomato and pickles, stacked like a burger on toasted bread. | Say “Cheeseburger sub” so they know it’s not a regular burger |
| Sicilian | An Italian stacked with meatballs, mushrooms, marinara, provolone and hot peppers. | Say “Sicilian” or list the toppings |
| Black and Bleu | Roast beef with bleu cheese, lettuce and tomato. Simple and sharp. | Say “Black and Bleu”; availability varies |
| Chicken Cordon Bleu | Grilled chicken, ham and Swiss with toppings. A deli classic, Potbelly style. | Say “Chicken Cordon Bleu” |
| Barnyard | A Wreck packed with crispy bacon and meatballs. Added to the Underground Menu in March 2025. | App only, order it from the Underground Menu tab |
| The Elvis | A PB&J with added bananas and crispy bacon. Sweet, salty and completely unserious. | Order a PB&J, then ask to add bananas and bacon |
The lineup can shift, Potbelly added the Barnyard as recently as March 2025, so check the app tab again if something’s missing.
How Do You Order From the Potbelly Underground Menu?
Ordering from the Potbelly Underground Menu is easiest in the app, but it works in-store too. In the Potbelly app, switch to the Underground Menu tab and the full lineup appears with pictures and exact pricing for your location. Tap, customize, done.
Walking in? Just order by name. “Can I get a Lucky 7, Original size, toasted?” works at most shops because these names have been around for years and staff know them. If you get a blank stare, and it happens, no big deal. Just describe the build instead: “Can I get a Wreck with meatballs, Swiss, mayo, lettuce and tomato?” Every item on the list is made from ingredients Potbelly already stocks, so they can build any of them.
A few ordering tips that make life easier. First, know your size. Every sandwich, secret or not, comes as Original, Big (about a third more of everything) or Skinny (about a third less). Second, keep it short during the lunch rush. A regular will happily build you a Wrecking Ball, but maybe save the five-modification custom job for 2pm. Third, double meat is available on every sandwich for a few extra bucks if you’re feeling ambitious.
Does the Potbelly Secret Menu Cost Extra?
Potbelly secret menu prices are basically in line with the regular menu, since they’re built from the same ingredients. What you pay depends on your location and the size you pick, with Bigs costing more than Originals. The app shows the exact price for your shop, so there’s no guessing.
The app shows the exact number for your shop before you order, so there are no surprises at the register.
Is the Potbelly Secret Menu Available at Every Location?
Through the app, yes. The Underground Menu tab works at every Potbelly that takes app orders, and app-exclusive items like the Barnyard are only available that way. In-store is a little less certain. Most locations know the big names like the Lucky 7 and the Sicilian, but some staff at quieter shops may never have heard them.
That’s not a dead end, though. Because every secret item uses standard ingredients, any location can make one if you describe it. The one exception to watch is the Black and Bleu, which has had limited availability, and the PB&J based Elvis, which depends on the shop stocking bananas. When in doubt, a quick call ahead saves a wasted trip.
Which Potbelly Secret Menu Sandwich Should You Try First?
Okay, opinion time. If you only try one, make it the Lucky 7. It’s the most “greatest hits” of the bunch, half Wreck and half Italian, and it tastes like someone let the sandwich makers off the leash. Big appetite? The Wrecking Ball is the heavyweight, meatballs on top of an already loaded Wreck.
For something different, try the Elvis. Peanut butter, banana and bacon sounds wrong until you bite into it. My ranking: Lucky 7 first, Wrecking Ball second, Sicilian third.
