Starting May 13, Wonder Steak's Himeji branch is running a weekday lunch promotion: a free 20g increase on its popular "Otoro Beef Steak" for customers who order M size or above.
What Is Wonder Steak?
Wonder Steak is a restaurant chain built around the concept of enjoying authentic steak for 1,000 yen until you are completely full. By operating its own meat processing factory (central kitchen), the chain achieves large-scale purchasing and production that keeps steak prices affordable. Rice, miso soup or soup, side dishes, and pickles are all available for unlimited refills, so guests can eat to their heart's content.
The Signature "Otoro Beef Steak"
The "Otoro Beef Steak" is a cut that showcases the sweet richness of beef fat from the very first bite. Guests who enjoy marbled, well-marbled cuts will find this steak particularly satisfying.

20g Increase Campaign
To give customers a full taste of this featured menu item, Wonder Steak Himeji is adding 20g to every "Otoro Beef Steak" order of M size or above at no extra charge.
Plus-On Toppings at Half Price
Popular add-on topping items are also on offer at half the regular price when ordered alongside a steak:
- Genkotsu Hamburger: Normally ¥1,000 (tax excluded) → ¥500 (tax excluded)
All-You-Can-Eat Sides
Rice, miso soup or soup, side dishes, and pickles remain available for free refills throughout the meal, as per the restaurant's standard offering.
Grand Menu at Himeji
The Himeji branch offers three types of 1,000-yen steaks, along with a mixed set (half-and-half) that lets guests sample two different cuts at once. The king-size "Rib Roast" steak draws plenty of orders, and long-standing menu items such as the "Harami Steak" and "Fillet Steak" remain popular choices.
