Welcoming a new year is often about small rituals that bring comfort, meaning, and a sense of optimism. In Singapore, food has always played a big part in that ritual, whether it is gathering with family, catching up with friends, or simply treating oneself after a long year. As 2026 approaches, MOS Burger Singapore is marking the occasion with a seasonal offering that feels both indulgent and symbolic, combining a much-loved premium savoury item with a dessert rooted in Japanese New Year tradition.
For those who have followed MOS Burger over the years, the return of the Premium Unagi Rice Burger is always something to look forward to. It does not appear often, and when it does, it tends to disappear quickly. This time, MOS Burger is pairing it with the Lucky Nasubi Matcha Mochi, a thoughtfully designed dessert inspired by Japanese culture and New Year beliefs. Together, they create a limited-time promotion that is not just about eating well, but also about starting the year with positive meaning.
The Premium Unagi Rice Burger stands out because it is unlike a typical fast-food burger. Instead of bread buns, MOS Burger uses their signature compressed rice patties, lightly grilled and seasoned to hold their shape while staying fragrant and comforting. Between these rice layers sits the real highlight: rich, savoury unagi. The eel is glazed, tender, and flavourful, delivering a depth that is usually associated with sit-down Japanese restaurants rather than quick-service dining.
What makes this burger especially satisfying is the attention to detail in its construction. The unagi is layered over fragrant nori, adding a gentle sea aroma, while shredded tamagoyaki brings a soft sweetness that balances the savoury eel. Each element has a purpose, and nothing feels excessive. The rice patties soak up the sauce just enough, ensuring every bite tastes complete rather than messy.
To elevate the experience further, MOS Burger includes a packet of sansho pepper with every Unagi Rice Burger. This is not just a garnish. Sansho has a citrusy, mildly spicy profile that cuts through the richness of the eel. Sprinkling it over the burger transforms the flavour, adding brightness and a gentle tingle that keeps the dish from feeling too heavy. It is a small touch, but one that reflects how Japanese cuisine values balance and nuance.
For those who want something even more indulgent, the Unagi Tamago Rice Burger offers an enhanced version with an extra layer of egg. The tamagoyaki adds softness and a subtle sweetness that complements the savoury eel beautifully. This variation is particularly appealing to diners who enjoy richer textures and a more filling meal, especially if it is meant to be a celebratory treat rather than a quick bite.
While the burger is clearly the main attraction, the Lucky Nasubi Matcha Mochi deserves just as much attention. This dessert is inspired by “San-Nasubi” (eggplant), one of the three auspicious symbols traditionally associated with Hatsuyume, the first dream of the Japanese New Year. According to the proverb “Ichi-Fuji, Ni-Taka, San-Nasubi,” dreaming of an eggplant is believed to bring good fortune. MOS Burger has turned this cultural reference into a charming, edible form.
The Nasubi Matcha Mochi is shaped and coloured to resemble a small purple eggplant, making it visually distinctive and thoughtfully designed. Inside, the mochi is filled with a combination of sweet mung bean paste and matcha. The sweetness is gentle rather than overpowering, while the matcha adds a light bitterness that keeps the dessert balanced. The mochi skin itself is soft and chewy, making it a comforting end to the meal.
Beyond taste, this dessert adds a sense of playfulness and meaning. Eating a San-Nasubi-inspired mochi at the start of the year feels like a small, symbolic way to invite good luck and positivity into the months ahead. It is the kind of detail that makes this promotion feel considered rather than generic, especially for those who appreciate Japanese culture or enjoy seasonal food experiences.
To complete the meal, MOS Burger has also curated combo sets that make the promotion more convenient and value-driven. The Unagi Tamago Rice Burger Combo includes the enhanced burger, a Lucky Nasubi Matcha Mochi, and a bottle of Ayataka Japanese Green Tea. The tea is light, refreshing, and helps cleanse the palate, making it a sensible pairing with the rich flavours of unagi. For those who prefer something slightly lighter, the Unagi Rice Burger Combo offers the classic version of the burger alongside the same dessert and green tea.
From a value perspective, opting for the combo sets allows diners to experience the full range of what this promotion offers without having to choose between savoury and sweet. It also makes the meal feel more complete, especially for those visiting during lunch breaks or casual dinners.
So why should they make the effort to enjoy this deal? Firstly, the Premium Unagi Rice Burger is one of MOS Burger’s most premium and rarely available items. Its return is always limited, and missing it often means waiting a long time before it comes back again. Secondly, the Lucky Nasubi Matcha Mochi is exclusive to this seasonal promotion, making it a one-off experience tied specifically to the New Year period.
There is also something comforting about starting the year with a meal that combines indulgence and symbolism. After a busy year, taking a moment to enjoy a thoughtfully prepared burger and a culturally meaningful dessert can feel like a small reset. It is suitable for solo diners looking for a quiet treat, colleagues grabbing lunch together, or friends meeting up to welcome 2026 in a relaxed way.
Finally, with availability across all MOS Burger outlets islandwide, this promotion is accessible without needing special plans. Whether it is a planned visit or a spontaneous stop, the Premium Unagi Rice Burger and Lucky Nasubi Matcha Mochi offer a simple yet memorable way to mark the start of the year.
For anyone who enjoys Japanese flavours, seasonal menus, or simply a good limited-time deal, this New Year promotion is worth making time for before it disappears.
