About Smashburger
While Smashburger is a fast casual chain built on smashed-to-order burgers, sides and shakes across company-run and franchised locations, customers of chains like this one meet a familiar set of issues: orders that arrive missing items or made without a requested change, food that has gone cold or soggy by the time a courier delivers it, menu prices on delivery apps that sit well above the in-store price, waits that stretch at lunch and dinner peaks, and locations that quietly close while still showing as open online.
Confirm the order at the counter and check a delivery bag on arrival, since a photograph taken straight away supports a refund. Refunds for app orders usually come from the delivery platform, not the restaurant. Keep the receipt or order number, and check opening hours before traveling to a location you have not visited recently.
Turned up to a location that shows open online? Log it with us. Other customers who made the same trip can back the case up and add what they found there.

Common customer service questions about Smashburger
How do I file a complaint about Smashburger?
Do you have a dispute or a bad customer experience with Smashburger? Report it through our website to maximize the chance of getting it resolved.
We help you write an effective complaint in minutes. Our AI models are trained on thousands of effective complaint letters. Then we push it through emails, social media, paper complaint letters and other tools at our disposal. And you are not alone: our helpful community is there for advice.
How do I contact Smashburger customer service?
You can reach Smashburger by phone on 801-712-8299. The written routes are the contact page reached from the footer of smashburger.com and the help section behind its questions and answers. Order problems, account and login problems and rewards questions each have their own address there, so choose the one that matches instead of sending everything to the general route.
Give the location, the date and time, the order number and the amount charged. Smashburger runs company operated restaurants alongside franchised ones, so naming the location is what decides who ends up being asked about it.
Change you asked for at the counter, paid for and missing from the order? Start your complaint on our website and we take it out to Smashburger by email, across social media and in printed letters.
How do I report a missing or wrong item in a Smashburger order?
Report a missing or wrong Smashburger item on the day of the order, through whichever service took your money. A courier delivery is settled by the delivery platform from its own order history, an order placed at the counter or on a kiosk is settled by the restaurant that made it, and the two do not refund for one another.
Photograph the bag and its contents before anything is unwrapped or thrown out, and keep the receipt or kiosk order number, which is what identifies the ticket in the kitchen. A special request that never reached the kitchen is worth mentioning separately from a missing item, because the two are logged differently and a restaurant can only fix what it can see went wrong.
Why are Smashburger prices higher on delivery apps than in the restaurant?
Menu prices on third party delivery apps are commonly set above the in-restaurant price, which is how restaurants absorb the commission the platform charges them. That markup sits inside the item price, and the delivery fee, service fee and tip are added on top of it, so the gap between eating in and ordering in can be much wider than it first looks.
Compare the same item in the Smashburger app or on the menu at the restaurant before you order, and use pickup if the difference matters to you. If an app charged more than the price it displayed at checkout, that is a different problem: screenshot the basket, keep the confirmation email, and raise it with the platform that took the payment.
What can I do if a Smashburger location has closed?
Check the location finder on smashburger.com before travelling, because third party maps and listing sites are the last to be updated when a restaurant closes. A quick look at recent reviews or a call to the number on the listing usually settles it faster than the listing itself.
A rewards balance sits with your Smashburger account rather than with one restaurant, so it does not disappear when a location shuts, although the nearest place to spend it may change. An order you already paid for at a closed location through a delivery app is refunded by that app, from the order history.
Location listed as trading and shuttered when you got there? Start it through our complaint process, and the next diner who checks that listing before driving over can find your case and see what happened.
