MOS Burger is a Japanese hamburger chain, described on its own site as premium and known for a wide variety of unique and original tasting burgers. Founded in 1972, MOS Burger has kept its original policy and passionate commitment to creating delicious, quality burgers even as its menu and style have evolved, and the brand now serves customers well beyond Japan.
Every burger is prepared only upon a customer's order, rather than made in advance, so it can be enjoyed at its freshest. MOS Burger also says it hand-prepares vegetables every morning in-store instead of using pre-packed factory vegetables, using more vegetables in its burgers as part of its focus on quality and freshness.
Alongside the classic MOS Burger outlets, the brand also runs MOS Burger Express, a simplified, grab-and-go format offering healthier, fuss-free, tapow-friendly meal options such as sandwiches and onigiri, on top of MOS Burger favourites like the fish burger and teriyaki chicken burger.
In Singapore, MOS Burger can be ordered for delivery through Grab and foodpanda, or via the brand's own app, and customers can also join the MOS Rewards program.
MOS Burger has been making burgers since 1972, and describes itself as a premium Japanese hamburger chain built on a straightforward idea: every burger is prepared only once a customer orders it, so it's served at its freshest rather than sitting under a heat lamp. Vegetables are hand-prepared in-store every morning rather than arriving pre-packed from a factory, and the brand uses more vegetables in its burgers as part of that same commitment to quality.
MOS Burger's menu spans well beyond a standard beef patty. The core burger line-up ranges from the classic $2.70 Hamburger and $4.30 MOS Burger up to newer additions like the Firery Wagyu Cheeseburst ($9.45), Roasted Garlic Chicken Burger ($9.45), Tokyo Hamburg ($7.95) and Avocado Wagyu Burger ($8.10). There's also a Deluxe Mushroom Wagyu Burger ($8.10), Teriyaki Chicken Burger ($4.95), Ebi Katsu ($4.95), Fish Burger ($4.30), Spicy MOS Burger ($4.55), Chicken Burger ($4.85), Teriyaki Beef Burger ($4.30), Hokkaido Croquette Burger ($4.10) and Cheese Burger ($3.10).
What sets MOS Burger apart from a typical Western burger chain is its rice burger line — a Japanese format that swaps the bun for grilled rice patties. The Okonomiyaki Rice Burger ($6.75), Yakitori Rice Burger ($4.95), Yakiniku Rice Burger ($4.95) and Kakiage Rice Burger ($4.95) bring distinctly Japanese flavours into a familiar burger format. For those after something different again, the Natsumi range serves the same fillings — teriyaki chicken, fish or beef — as a Wedge Salad Burger, priced between $4.20 and $4.85, alongside a small Hot Dogs selection: Plain ($4.30), Chili ($4.55) and Spicy Chili ($4.70).
Sides round out the menu with options like Hokkaido Corn Soup and Clam Chowder (both $3.90), Chilli Crab Mantou ($4.50), Teriyaki Mayo Fries ($4.70), French Fries in small ($2.80) or large ($3.80), MOS Chicken ($3.90), Green Salad ($2.80) and Hokkaido Croquette Pie ($2.80). Shareable options include Chicken Nuggets (6pcs for $5.10, 15pcs for $11.00), Butterfly Prawns (6pcs for $5.20, 15pcs for $11.10) and Mussel Nuggets (4pcs for $4.30, 10pcs for $9.35).
On the drinks side, MOS Burger offers a full spread of cold options — Iced Tea, Iced Lemon Tea, Coca-Cola, Coca-Cola Zero, Fanta Grape, Minute Maid Refresh Orange, Authentic Tea House Ayataka and Iced Cocoa — alongside hot drinks including Freshly Brewed Gourmet Coffee, Hot Cappuccino, Hot Latte, Hot Tea, Hot Lemon Tea and Hot Cocoa, most priced between $3.20 and $4.40.
For a faster option, MOS Burger Express offers a simplified, grab-and-go version of the regular outlets. It's built around healthier, fuss-free, tapow-friendly meals like sandwiches and onigiri, alongside MOS Burger favourites such as the fish burger and teriyaki chicken burger — a good fit for anyone who wants MOS Burger's flavours without sitting down for a full meal.
Since its founding in 1972, MOS Burger's menu and style have evolved, but the company describes its core policy and commitment to creating delicious, quality burgers as unchanged. The brand has expanded well beyond Japan, bringing its approach to burgers to countries around the world, including Singapore.
In Singapore, MOS Burger can be ordered for delivery through Grab and foodpanda, or through the brand's own app. Customers can also join the MOS Rewards program for ongoing perks, and can follow MOS Burger Singapore on Facebook and Instagram for updates on new items and promotions, such as recent Chilli Crab Festival, Salmon Rice Burger and Ebi Katsu Burger launches.
