Mo-Mo-Paradise

A historic AYCE shabu-shabu chain belatedly makes its way from Japan (and LA) to Orange County

When Mo-Mo-Paradise opened its first location in Japan three decades ago, the idea of all-you-can-eat shabu shabu – boiled meats and vegetables served with dipping sauces – was so novel that the business’s very name signaled luxury to local audiences: “Mo mo” is the Japanese onomatopoeia for a cow’s moos, suggesting that the restaurant’s fixed price access to nearly unlimited meats would be heaven for beef lovers. Having visited a location in Tokyo roughly 15 years ago, we can attest that it certainly seemed special at the time, but the world has changed a lot since then: Chubby’s chains of quasi-luxury and high-end AYCE wagyu restaurants more decadently cater to the same audience, with All That Shabu, dPot, Dada Shabu Shabu, and Shinobu offering wide spreads of mid-tier meats at lower prices.

This isn’t to say that Orange County’s first location of Mo-Mo-Paradise is unwelcome – it’s just locally quite late to the craze it sparked in Japan back in 1993, and with its first US location in Rowland Heights nearly a decade ago, in early 2016. Replacing House of Shabu Shabu, which sadly burned down in mid-2023 at Irvine’s Orange Tree Square plaza, Mo-Mo now offers a mostly straightforward AYCE experience with two tiers: Momo ($30/person weekday lunch, $39/person dinners/weekends/holidays), and Wagyu ($55/person dinners/weekends/holidays). Momo offers 90 minutes of unlimited access to four sliced meats (chuck eye, boneless short rib, eye of round, and Kurobuta pork shoulder) at lunch or five (adding pork belly) at dinner, with the Wagyu tier offering three similar beef cuts (chuck eye, rib, and round) in fattier American wagyu variations. Guests can choose two of four total broths per table, including light tomato and pork tonkotsu broths, traditional dashi shabu shabu, or sweet and savory sukiyaki. Our photos show the tonkotsu and tomato broths, which arrive in a yin-yang boiling pot for cooking meats alongside bowls and bottles of ponzu, sesame gomadare, and spicy miso dipping sauces.

Two of Mo-Mo’s major competitive differentators are its self-serve buffet (“Farmer’s Market”) and beverage selection (“Drink Garden”), the former included with all meals, and the latter offered as an all-you-can-drink pairing for $3.55. While the buffet is quite limited by comparison with Mo-Mo’s rivals – almost everything is intended to be cooked shabu-style along with the meats – there’s a nice, large pot of wagyu beef curry and unlimited rice to snack on while you’re boiling meats, veggies, and noodles, plus three server-scooped ice creams for dessert; edamame and a salad are also available all day, with yuba rolls joining the collection during premium pricing hours. The steal of the meal is the Drink Garden, which includes access to four really nice dairy and dairy-free teas, seven premium sodas, and three toppings (azuki beans, coffee jelly, and lychee jelly). You can make your own drinks for way less than at plaza neighbors Heytea and Wushiland Boba, so we’d certainly recommend splurging for this add-on.

Another major difference with Mo-Mo-Paradise is the more authentically Japanese environment, which eschews Chubby Group’s over-the-top decor, hyper-aggressive service, and more elite plating for a more minimalist experience. Mo-Mo servers attend respectfully and reasonably to guests across the roughly 100-person dining room, which uses traditional and fairly neutral Japanese tile, stone, and wood motifs to accommodate everyone from families and friends to business colleagues in a clean, well-lit space that thankfully keeps attention on the food and people, rather than on dark, moody rooms, or on the plaza parking immediately outside.

The good rather than eye-popping approach extends to Mo-Mo’s proteins. Each meat arrives as four to six thin slices in hard plastic trays, just thick enough to survive individual or group removal without shredding. Beyond the 90-minute maximum, there are no explicit limits on how much you can order at once, nor are penalties listed for either over-ordering or failing to finish ordered items; this isn’t always the case at rival chains.

How much you’ll like or love the food at Mo-Mo depends on both your appreciation for shabu-style cooking and your use of the included and optional sauces. The broths we sampled were both relatively mild in flavor and in no way salty, only lightly enhancing the meats and vegetables we boiled; this left Mo-Mo’s good but unremarkable ponzu, sesame, and miso dips as the major impactors for each bite. Buffet bowls of spicy shoyu sauce, chili paste, green onion, grated daikon, sesame seeds, and chili flakes are also available to punch up either the sauces or dipping broth as you prefer; otherwise, you can just savor the natural flavors and textures of the meats, which in our view were all tasty without any need to add the excessive fat of wagyu options. Vegetable, noodle, and fishball choices here are more limited than at other chains, with very little seafood, if that matters in your decision; we were pretty satisfied with what we had.

Mo-Mo’s included ice creams are fine. We tried the mint chip and cherry flavors, skipping only vanilla, and received small, hard-packed ice cream scoops that catered to “not too sweet, not too strong” tastes. While we tend to preserve self-dispensing soft-serve at AYCE places, there was again no stated limit on how much ice cream we could have ordered if we’d wanted more.

At dinner prices – and even with the addition of fatty pork belly and yubu rolls – our impressions of Mo-Mo-Paradise might have been different. As a $30 weekday lunch option, this restaurant isn’t cheap, but delivers pretty good AYCE value in a nice environment. That said, Irvine rival Dada offers more choices (including a much larger buffet) for around the same price. For $38 without drinks at dinner time, Mo-Mo becomes a little harder to justify, and if you’re seeking wagyu, the $55 option (again, without drinks) would be hard to recommend over Mikiya’s comparably priced entry tier, which includes both drinks and many more food options.

With plenty of recently opened local AYCE shabu competition, it will be interesting to see how each of these places adapts, and we’re glad the authentically Japanese Mo-Mo has finally come to Orange County. Whether we’ll return in the future will depend on how the menu and pricing evolve over time.
