Dinner at Niku Japanese Grill is something the table cooks for itself. A grill is set into each table, much of the food arrives raw and by the round, and the all-you-can-eat format leaves the pacing to the diners rather than the kitchen. Yakiniku run this way alongside a full sushi and sashimi menu is a rare combination in downtown Orillia, where Japanese cooking has more often meant a fixed roll list and a quieter meal. Niku treats the format as an event rather than a transaction: proteins ordered in waves and seared over the tabletop grill, paced against rounds of rolls and raw fish until the table decides it has had enough. One sitting can move from short rib to sashimi and back without anyone leaving the format.
The grill side is where the menu shows its hand. Beef leads it—Toro Beef Tare marked for heat, Beef Short Rib, ribeye steak, and hand-cut beef flank—with pork belly offered in both thin and thick cuts for the table to take how it wants them. Chicken breast, lamb, shrimp, and salmon fillet widen the range for groups looking past beef, and a cheese-and-pork Japanese sausage sits in the mix for anyone building a plate past the obvious cuts. The proteins come out raw to be cooked at the table, which changes the rhythm of the meal: nothing is finished when it lands, and the first round sets the pace for everything after it. It is a lot to work through, which is rather the point—the yakiniku list is written for a long sitting, not a single order.
The sushi and raw bar hold up their end. Rolls run from a Rainbow Roll layered with tuna and salmon over crab, cucumber, and avocado, to the shrimp-tempura Green Dragon and Red Dragon, a Dynamite Roll of shrimp tempura and crab, and a Philadelphia of smoked salmon and cream cheese. Sake Salmon Sashimi gives the table a clean seafood pause between grill rounds, and the maki list stretches to spicy salmon and torched salmon for anyone working the raw side hard. There is a Super California Roll under crab and spicy mayo, ramen and rice bowls like Yakiniku Don for diners who want something hot and finished, and lighter anchors—miso soup, edamame, gyoza—for the gaps between. A mango pudding closes it out.
What the menu describes is a meal built for pacing, and Niku sets up to match it. Reservations are taken online, which suits the way the format is meant to work—a planned group sitting rather than a quick in-and-out, with time to run the grill in rounds and trade favourites across the table. The all-you-can-eat model rewards a table that arrives ready to spend a couple of hours on it, ordering in waves and letting the grill reset between courses. That it favours the group over the solo diner is built into the design. Even the service leans into the occasion: a robot server ferries plates through the dining room, a piece of theatre that reads as part of the night out rather than a gimmick bolted onto it.
Niku opened in 2024, one of the newer arrivals on a downtown Orillia strip that had not carried much like it. What it offers is abundance handled with some care—a grill the table runs itself and a sushi list broad enough to keep the raw-fish crowd busy while the beef works through its rounds. For a group deciding where to spend a Friday night on Front Street, that breadth—and the fact that everyone at the table builds the meal they want from it—is the whole appeal.
Niku is strongest when treated as a shared table-cooking meal, with yakiniku proteins such as Toro Beef Tare, Beef Short Rib, ribeye, pork belly, chicken, lamb, shrimp, and salmon fillet shaping the night.
The menu gives sushi fans enough room to roam, from sashimi and salmon sushi to Rainbow Roll, Green Dragon Roll, Red Dragon Roll, Dynamite Roll, Philadelphia Roll, and mango-salmon combinations.
Online reservations, all-you-can-eat pacing, and a robot server hook make the restaurant a practical choice for a planned Orillia group meal rather than a quick in-and-out stop.
