Best Smashburger x Züri Isst + Delivery

‘BUNZAI’ and the Wolf - Special collab burger by Züri isst / Pascal Grob

We’re excited to announce a special collaboration with Züri Isst and JustEat—a unique opportunity that finally brings BUNZAI to delivery!

Why Haven’t We Done Delivery Before?

If you know us, you know we’ve resisted delivery for a long time, despite strong demand. Here’s why:

• High commissions (20–30%)—most restaurants pass this cost onto customers.

• Extra delivery fees (ca. CHF 5.0) on top of that.

• Limited kitchen capacity—we simply couldn’t handle it without affecting quality.

Ultimately, it boiled down to customer experience. We didn’t want you paying more than CHF 40.- for a burger that arrives in less-than-perfect condition, with no way for us to fix it.

What has changed?

For the next two months, we’re offering delivery exclusively via JustEat, thanks to their partnership with Züri Isst.

• Lower commissions for us, meaning only small premium per burger compared to in-store - fries & drinks stay the same price as in-store.

• Free delivery for you.

• More kitchen capacity during the colder months, making this the perfect time to test it.

But There’s More — The Special Züri Isst Burger

We originally planned a low-key winter with just in-house specials, but this collab felt too good not to celebrate properly. So, we teamed up with Pascal Grob, aka Zurich’s favorite food blogger, to create something special.

Together, we crafted a pepper jelly paired with miso-mayo, toasted sesame seeds, pickles, diced onions, and shredded lettuce—a perfect balance of sweetness, umami, and freshness.

The inspiration comes from a restaurant he visited on his recent trip to New Orleans. Find out more about his inspiration here.
