Smashburger
Smashburger
Smashburger is an American fast-casual restaurant brand specializing in made-to-order burgers, chicken sandwiches, fries, shakes, salads, and other casual food. The concept was founded in Denver, Colorado, in 2007 and became known for its cooking method in which burger patties are pressed or “smashed” on a hot grill to create a seared exterior while retaining moisture inside. Current brand information states that its burgers use 100% Certified Angus Beef.
Smashburger has expanded beyond Colorado into multiple U.S. states and international markets. According to Jollibee Group reporting, Smashburger had 214 stores in six countries and territories as of December 31, 2024, including the United States, Canada, the United Kingdom, Costa Rica, Saudi Arabia, and Egypt. The brand operates a mix of corporate and franchised restaurants.
Smashburger is fully owned by Jollibee Group, a multinational restaurant company based in the Philippines. Jollibee initially acquired a stake in Smashburger in 2015 and completed full ownership through additional acquisitions, ultimately becoming the sole owner. Current Smashburger and Jollibee materials both confirm that the brand remains fully owned by Jollibee Group.

For a problem involving a restaurant order, refund, staff interaction, missing food, food quality, or pickup, the most effective first step is to contact the restaurant directly. Smashburger’s official FAQ specifically tells customers to contact the restaurant or use the Contact Us page when reporting an order problem or requesting a refund.
When using the online Guest Support portal, include the store number, restaurant name, city and state, date and time of purchase, total amount, last four digits of the payment card, and a copy of the receipt if available. Smashburger specifically asks customers to provide these details to improve investigation and resolution.
If the transaction was placed through DoorDash, Uber Eats, Grubhub, or another third-party delivery platform, contact that platform when the issue involves the delivery service or a platform-controlled refund. For broader corporate correspondence, use the Denver office at 3900 East Mexico Avenue, Suite 1200, Denver, CO 80210.
Complaints may involve food quality, restaurant service, refunds, incorrect orders, delivery, Rewards, gift cards, billing, or employee behavior. Before escalating, gather your receipt, store number, city and state, order date and time, payment details, delivery information, photographs where useful, and any previous case history.
Start by contacting the restaurant directly or using Smashburger’s official Guest Support portal. For active restaurant problems, local management can often correct the issue immediately. Provide all transaction details and clearly state whether you are requesting a refund, replacement, credit, or another resolution.
If the order was placed through a third-party delivery service, contact that provider for platform-controlled delivery or refund issues. Gift-card questions should use Smashburger’s gift-card support process, while franchise inquiries should use the franchise-development contact rather than Guest Support.
If the first restaurant employee cannot resolve the complaint, ask for the General Manager or another senior manager. Provide the original receipt and explain all previous attempts at resolution. Keep the manager’s name and any commitment to follow up.
Submit the complaint through the official Contact Us page. Include the information specifically requested by Smashburger, including restaurant details, transaction date, amount, payment-card last four digits, and receipt. This creates a documented corporate support record.
If the issue remains unresolved, send written correspondence to Smashburger, 3900 East Mexico Avenue, Suite 1200, Denver, CO 80210. Include a concise timeline, copies of receipts, previous correspondence, and the exact resolution requested.
For a legal, franchise, privacy, gift-card, or other specialized dispute, ask the company to route the complaint to the department responsible for that issue. Review the current Terms before sending formal correspondence because digital-service and gift-card matters may have separate conditions.
Food-safety or sanitation complaints should be directed to the local or state health department responsible for the restaurant. Employment issues may involve state or federal labor agencies, while accessibility complaints can involve the appropriate civil-rights authority.
If the restaurant does not resolve a disputed charge, contact your card issuer or payment provider. You may also file a general consumer complaint with the appropriate state Attorney General or consumer-protection agency.
For a significant unresolved dispute, review Smashburger’s current Terms and Conditions to determine whether arbitration, small claims court, or another legal process applies. Preserve receipts, screenshots, Guest Support records, written responses, and proof that internal escalation was attempted first.
