When it comes to grabbing a quick, satisfying bite that doesn’t compromise on flavour, MOS Burger has long been a favourite among fans of Japanese-style fast food. Now, for those looking to enjoy something a little different from the usual burger fare – and save a bit while they’re at it – this latest offer from them is just the thing to perk up the start of your week.
Starting from 8 July 2025, MOS Burger Singapore is offering their signature Oyako Rice Burger for just $5.50 (ala carte) every Monday and Tuesday at selected outlets. This is a fantastic markdown from the usual price of $6.30, and it’s available for a limited time only. It’s not just a typical burger promotion – it’s a taste of Japan at an incredibly wallet-friendly price.
For those unfamiliar with this special burger, the Oyako Rice Burger is a unique twist on the traditional hamburger. Instead of a conventional bread bun, it features warm and fluffy rice patties that sandwich a delicious Japanese-style omelette paired with a savoury slice of nori seaweed. It’s a comforting combination that delivers on both flavour and texture – and with this promotional price, there’s even more reason to give it a try.
So why should people take notice of this deal and make it a part of their weekly food plans? Here’s a deeper look into what makes this promotion worth a visit.
An Affordable Introduction to Japanese Fusion Fast Food
Singapore’s food scene is known for its diversity and global influences, and MOS Burger has played a part in bringing Japan’s take on fast food to local shores. While sushi, ramen, and tempura have long been popular choices, rice burgers bring something new to the table – they’re uniquely Japanese, yet practical and convenient enough for a Singaporean lifestyle.
The Oyako Rice Burger stands out for its combination of traditional Japanese flavours with the modern convenience of grab-and-go dining. The name “Oyako” translates to “parent and child,” which usually refers to chicken and egg – a beloved pairing in Japanese cuisine. It’s a humble but comforting dish, and MOS Burger manages to serve it up in burger form with a distinct flavour profile.
By pricing this burger at only $5.50 on Mondays and Tuesdays, MOS Burger makes it accessible for more people to enjoy something different, especially during the week when a light, flavourful meal might just be the pick-me-up people need.
Why It’s More Than Just a Burger
It’s not just about saving $0.80 off the usual price – it’s about experiencing something that’s a little out of the ordinary. The rice patty bun alone is a big departure from the usual sesame bun. It’s soft but firm enough to hold the fillings, offering a satisfying bite without being too heavy. The Japanese omelette in the middle adds richness, while the nori lends a savoury depth and subtle crunch.
It’s a great choice for those who are looking to reduce their bread intake without giving up on enjoying a burger. And since it’s served ala carte, it’s ideal for those who want a quick and simple meal, or even pair it with their own drink of choice.
Perfect for a Quick Bite – with Substance
For busy professionals, students, or anyone on the go, the Oyako Rice Burger fits easily into a lunchtime break or a quick dinner option. It’s satisfying without being too rich, and with MOS Burger outlets scattered across the island, convenience is a key advantage.
What’s more, MOS Burger’s reputation for consistency and quality makes them a reliable option. Even though this deal is available only at selected stores, the standards of preparation remain true to what they are known for – clean flavours, well-prepared ingredients, and a tidy presentation that reflects their Japanese roots.
A Midweek Ritual Worth Keeping
There’s something reassuring about a weekly tradition – and for those who love Japanese food, this could easily become one. Every Monday and Tuesday, diners can look forward to a reliably tasty and affordable option at their nearest participating MOS Burger store.
Having a weekday promotion like this also helps break up the monotony of weekly meals. It’s a reminder that even a fast-food lunch can feel special without costing too much. Whether dining alone, with a colleague, or grabbing takeout for a simple dinner, it’s a treat that doesn’t feel indulgent on the wallet.
What to Know Before You Go
This deal is strictly available on Mondays and Tuesdays and only for the ala carte Oyako Rice Burger – no sets or combinations. Stocks are limited, so it’s best to head down early if you’re keen on securing your burger fix. Do also check which MOS Burger outlets are participating in the promotion, as it’s not available at every location.

For just $5.50, diners get something that’s both hearty and different from the usual fast food. It’s a nice way to enjoy authentic Japanese fusion without stretching one’s budget.
It’s also perfect for those looking to introduce friends or family to Japanese rice burgers for the first time. With such an accessible price, it becomes easier to experiment or try something new without the risk of disappointment.
Whether someone is a long-time fan of MOS Burger or curious about Japanese-style burgers, this promotion is a simple and delicious excuse to stop by and have a try.
