Mikiya Wagyu Shabu House
Orange County finally gets a great AYCE wagyu beef shabu shabu restaurant from Chubby Group
Having enjoyed Chubby Cattle BBQ, the all-you-can-eat wagyu beef BBQ restaurant chain with Los Angeles and (upcoming) Irvine locations, we knew that Las Vegas-based Chubby Group was capable of offering Orange County a better dining experience than Wagyu Factory – the expensive but underwhelming AYCE BBQ spaces it opened over the summer in Tustin and Lake Forest. With the successful October 2025 opening of sister concept Mikiya Wagyu Shabu House in Irvine’s Westpark neighborhood, Chubby’s OC operations are finally beginning to live up to their potential.
Mikiya offers AYCE wagyu beef with various frills at several tiers ranging from silver ($55 per person) to gold ($78) to diamond ($98) – each price discounted for paid members, and substantially reduced for kids, depending on their height (half-off under 51″, free under 39″ tall). The difference here is that the focus is on Japanese-style shabu shabu: After you’re seated in one of Mikiya’s dark, beautiful dining spaces at a table with a shared boiling surface, you choose from two of four soup broths, order proteins from a tablet, grab additional items (noodles, veggies, dips) from a buffet, then dunk your selections to cook them. Friendly servers seat you, introduce you to the tablet ordering process, then repeatedly check in to deliver meats and seafood, clear used dishes, and offer help as needed.
Most guests will find that Mikiya’s silver tier offers more than enough options for an excellent meal. Beyond buffet access to minced and curried wagyu, noodles, vegetables, tofu fortune bags, and mini-bowls of wasabi octopus, cooked squid, and seaweed salad, guests can order unlimited portions of beef, pork, chicken, and seafood from the tablet. Three types of thin-sliced Australian wagyu beef are star attractions, plus Japanese kurobuta pork and jidori chicken; cookable seafood platters with abalone, crab, scallops, fish, tiger shrimp, and oysters; raw sashimi dishes; carpaccio and hand rolls with salmon or yellowtail; fried chicken, shrimp, gyoza, fries, and buns. Silver guests may also choose one included “specialty” dish from five options – wagyu nigiri, wagyu tartare, wagyu bone marrow, sweet shrimp sashimi, or a bluefin tuna and uni hand roll – with each extra plate going for $6.
When we visited Wagyu Factory, we said that “raw or cooked, Wagyu Factory’s meat isn’t much to write home about” – but that’s thankfully not the case at Mikiya. Offered as a raw tartare, wagyu cubes with chopped avocado were rich and tasty, while even silver-tier silces of wagyu ribeye, shoulder, and brisket tasted excellent with the spicy miso broth we ordered; kurobuta pork absorbed its flavor and color even better. A house broth was closer to neutral, and meats submerged in it benefitted more from a spicy garlic and ponzu dipping sauce we made from ingredients at the buffet.
Mikiya’s seafood is equally fresh and plentiful, arriving in overwhelming quantities on the platter, and tasting great in raw sashimi, sushi, and carpaccio forms – the latter truffle oiled – as well as cooked in the broth. Guests seeking opportunities to go crazy on abalone and crab will have that option here, and though fish options are limited, the quality is solid enough to keep going even in the presence of wagyu. (At gold and diamond tiers, the wagyu shifts to Japanese and more premium Australian graded beef, if extra fat really matters to you.)
Other items were also hits, even if they weren’t as luxe as the sliced wagyu and seafood. An AYCE curry don offering – self-dispensed rice topped with either minced or curry wagyu – tasted delicious, even if it was using meat trimmings, and a similarly all-inclusive beverage station offered soda drinks, Calpico, milk tea, and a sweetened grapefruit jasmine green tea that we really enjoyed. Two flavors of self-dispensed soft-serve ice cream, strong coffee and sweet strawberry, were individually great ways to end a meal, though it may have been for the best that their central “mix” dispenser wasn’t working.
After walking away impressed by Chubby Cattle’s LA location, our later visit to the Tustin Wagyu Factory was dispiriting; it wasn’t clear whether Chubby Group would be able to pull off an equally impressive AYCE wagyu experience in Orange County without cutting corners. Now that Mikiya’s open in Irvine, it’s obvious that this restaurant group can indeed offer something better than its non-wagyu shabu peers – albeit at a higher price point. We’d certainly return for another round at Mikiya, and our enthusiasm has been renewed for Chubby Cattle BBQ’s OC opening later in 2025.
