If there’s one thing food lovers in Singapore appreciate, it’s a good value meal that offers more for less. And this month, fans of Japanese fast-food favourite MOS Burger have a little something to look forward to. From 20 to 25 May 2025, they are running a limited-time promotion that brings a bit of extra crunch to the table—literally.
MOS Burger is offering a Free Small Fries with every purchase of a MOS Chicken Set Meal, but this deal is not open to just anyone. It’s exclusively for existing MOS Members, making it a great time to enjoy the benefits of being part of their loyalty programme. If you’re a registered member on their app before 19 May 2025 at 11:59 PM, you’re in luck—you’ll receive an exclusive e-voucher granting you this tasty freebie.
What Makes This Deal Worth It?
In Singapore’s fast-paced dining landscape, it’s easy to overlook smaller, more focused promotions. But this one is particularly appealing for a few reasons.
First, MOS Burger has earned a reputation for offering meals that are both satisfying and a little different from the usual fast-food fare. Their Chicken Set Meal, often featuring their signature crispy chicken patty, fluffy rice burger bun, and a refreshing drink, already offers a complete and filling option. Throw in a free small fries and suddenly you’re looking at an even better value meal without paying anything extra.
Second, free food always feels better when it’s a reward for loyalty. By offering this perk only to those who’ve taken the time to download their app and register early, MOS Burger is creating a sense of exclusivity and appreciation for their existing customer base. It’s a small gesture, but one that encourages people to keep coming back—and be first in line for future promotions.
Third, for budget-conscious diners in Singapore, where every dollar counts, this limited-time deal gives a little extra incentive to choose MOS Burger over other lunch or dinner options during the promotion window.
How to Enjoy the Free Fries Promotion
The mechanics of the promotion are straightforward, and the process makes it easy to redeem the offer without fuss. Here’s how to ensure you don’t miss out:
-
Be an Existing MOS Member – Only those who have downloaded the MOS Burger app and registered an account by 19 May 2025 at 11:59 PM will qualify.
-
Look Out for the E-Voucher – MOS Burger will send out the e-voucher to eligible members through their app. No complicated forms or contest entries—just a simple voucher delivered directly to your mobile device.
-
Head Down to Any Outlet – This promotion is valid at all MOS Burger outlets in Singapore for in-store retail purchases. It does not apply to online or delivery orders.
-
Purchase the MOS Chicken Set Meal – Once in-store, select the MOS Chicken Set Meal from the menu. This typically includes their signature chicken burger, a drink, and now, thanks to this promotion, a free serving of small fries.
-
Present Your Voucher at Checkout – Before paying, simply flash the e-voucher on your app to the cashier. That’s it—you’re all set for a crispy bonus.
Why Try MOS Burger’s Chicken Set Meal
If you’ve never tried the MOS Chicken Set before, now is the perfect time. Known for their focus on freshness and quality, MOS Burger’s chicken option is a step above your average fast-food fare. Their patty has a lightly crisp coating with juicy, well-seasoned meat on the inside, offering that satisfying crunch and flavour you’d expect from a quality fried chicken sandwich.
The set meal usually comes with a cold drink, and with this promotion, the added portion of small fries completes the experience. Whether you’re grabbing lunch between meetings or having a relaxed dinner, it’s a solid meal that doesn’t disappoint.
An Extra Perk for App Users
This promotion also highlights why it’s worthwhile to be part of MOS Burger’s member programme. Their app isn’t just a convenient ordering platform—it’s a gateway to exclusive vouchers, early access to limited-time offers, and alerts on seasonal menu launches. If you’re someone who enjoys dining at MOS Burger regularly, having the app downloaded and staying logged in can pay off in more ways than one.
But Be Quick—It’s Limited to the First 750 Members
It’s worth noting that this isn’t an unlimited giveaway. The promotion is limited to the first 750 MOS Members who meet the registration deadline and receive the e-voucher. Once that redemption cap is hit, the offer ends—so don’t wait until the last day if you’re serious about enjoying the deal.
