This Classic Wisconsin Supper Club Is Home To A Legendary 160-Ounce Prime Rib

A steak this large almost sounds like a tall tale until it lands on the table. Deep in Wisconsin’s supper club country, one long-running restaurant has built its reputation on a prime rib that borders on legendary.

Diners arrive hungry and curious, eager to see the cut that has earned statewide fame and inspired more than a few ambitious attempts to finish it in one sitting. The atmosphere feels comfortably old-school, the portions generous, and the experience unmistakably Midwestern.

Decades after opening its doors, this beloved supper club still proves that classic cooking and big flavours never go out of style.

A Wisconsin Supper Club Tradition Since 1961

Long before farm-to-table became a buzzword, supper clubs were already doing something more important: feeding communities with pride. Black Otter Supper Club has been a cornerstone of Hortonville, Wisconsin dining life since its early years of operation, building a reputation that stretches well beyond Outagamie County.

Family-owned and deeply rooted in tradition, this establishment carries the kind of institutional knowledge that only decades of dedicated service can produce.

Located at 503 S Nash St, Hortonville, WI 54944, the restaurant draws regulars who return not just for the food but for the familiar rhythm of the experience. Wisconsin supper clubs occupy a genuinely unique space in American food culture, combining the warmth of a neighborhood tavern with the culinary ambition of a serious steakhouse.

Black Otter honors that tradition without apology, serving guests who understand exactly what they came for and leave thoroughly satisfied every single time.

Home Of The Famous 160-Ounce Prime Rib Challenge

Ten pounds of slow-roasted, bone-in prime rib sitting on a plate is not a dinner, it is a declaration. Black Otter Supper Club offers a prime rib challenge that reaches an almost mythical 160 ounces, a four-bone cut that commands respect before a single bite is taken.

Challengers who attempt the feat earn more than bragging rights; they earn a genuine sense of accomplishment in one of Wisconsin’s most celebrated dining arenas.

The challenge draws adventurous eaters from considerable distances, and the stories that follow are the kind that get retold at every family gathering for years. Even diners who have no intention of attempting the full challenge find themselves ordering generously, because the smallest available cut at Black Otter is already larger than the largest cut at most competing establishments.

Portions here are not inflated for spectacle; they reflect a genuine philosophy of feeding people well and sending them home satisfied.

A Classic Supper Club Atmosphere That Feels Timeless

Comfort is an underrated quality in a restaurant, and Black Otter Supper Club has it in abundance. The interior features the kind of wood paneling and warm, low lighting that instantly signals to your nervous system that it is time to slow down and enjoy the evening.

There is no trendy minimalism here, no open-concept kitchen theater, just a genuinely inviting space that prioritizes the guest experience above all aesthetic trends.

First-time visitors often remark that the space feels immediately familiar, even on their inaugural visit. That quality is not accidental; it is the product of decades of thoughtful ownership by Bob and Geri, who have shaped every corner of the room to feel personal rather than corporate.

The bar area offers comfortable seating while guests wait for their tables, and the overall flow of the space encourages conversation, relaxation, and the kind of unhurried dining that Wisconsin supper clubs have always championed.

Prime Rib Slow-Roasted To Tender Perfection

Patience is the secret ingredient in any great prime rib, and the kitchen at Black Otter Supper Club clearly has plenty of it. The roasting process develops a beautifully rendered exterior crust while preserving the deep, beefy moisture within, producing a cut that requires very little ceremony to enjoy.

A warm, richly flavored jus accompanies each serving, ready to revive the meat during the final, satisfying stages of the meal.

Diners who arrive early are rewarded with the full selection of available cuts, and regulars strongly advise reaching the restaurant by 4 PM to secure their preferred size before popular options sell out. The prime rib at Black Otter is not seasoned for spectacle; it is seasoned for flavor, with a restraint that lets the quality of the beef speak clearly.

Every bone-in cut arrives with the structural integrity of a properly aged, carefully handled roast that has been treated with genuine culinary respect throughout the entire cooking process.

A Destination Restaurant In Hortonville

Driving nearly an hour for dinner is a commitment most people reserve for truly exceptional meals, and Black Otter Supper Club earns that kind of devotion regularly. Guests arrive from Columbus, Green Bay, Appleton, and beyond, making the trip to Hortonville a deliberate choice rather than a convenient one.

That level of dedication from a loyal customer base says more about a restaurant than any award or accolade ever could.

Situated at 503 S Nash St, Hortonville, WI 54944, the restaurant operates Tuesday through Sunday with evening hours that accommodate both early diners and those who prefer a more leisurely start to their night out. The phone number for inquiries and large party arrangements is 920-779-6975, and calling ahead is particularly advisable for groups planning to attempt the larger prime rib cuts.

Black Otter does not accept standard reservations, but the bar provides a genuinely pleasant waiting area where the anticipation of dinner becomes part of the overall pleasure of the visit.

The Famous Prime Rib Challenge

Few eating challenges carry the credibility of one built around a genuinely superior cut of meat rather than sheer volume for its own sake. The Black Otter prime rib challenge offers multiple tiers, with a 116-ounce, three-bone cut earning challengers a commemorative T-shirt, and the full 160-ounce, four-bone version standing as the ultimate test of both appetite and determination.

Successful challengers describe the experience with a mixture of pride and disbelief that is entirely understandable given the scale of the undertaking.

One well-traveled diner who had previously attempted the famous 72-ounce steak challenge at the Big Texan in Amarillo, Texas, described the Black Otter prime rib as a superior cut in every meaningful respect. The challenge is taken seriously by the kitchen, which produces each massive roast with the same care and attention applied to every other cut on the menu.

Calling ahead to 920-779-6975 before attempting the larger cuts is strongly recommended, as the restaurant appreciates advance notice for orders of this considerable magnitude.

Loaded Baked Potatoes And Traditional Steakhouse Sides

A great steak deserves equally serious company on the plate, and Black Otter Supper Club approaches its side dish selection with the same thoughtfulness applied to its main courses. The restaurant offers nine distinct potato preparations, a variety so comprehensive that one enthusiastic diner memorably quipped that the menu read as though Wisconsin had quietly annexed Idaho.

From cheesy bacon mashed potatoes to crispy parmesan wedges, each option arrives as a genuine supporting player rather than an afterthought.

The cajun potato wedges have developed a devoted following among regulars, delivering a satisfying crunch and a warmly spiced exterior that pairs beautifully with the rich, savory depth of the prime rib. Potato skins are another strong contender, arriving properly crisped and generously loaded.

The breadth of the sides menu reflects a kitchen that takes comfort food seriously, understanding that Midwestern diners expect every component of their meal to deliver real satisfaction, not merely fill space on an otherwise impressive plate.

Where Generous Portions Are Part Of The Experience

Abundance is a philosophy at Black Otter Supper Club, not a marketing strategy. Portions arrive at the table in sizes that consistently surprise first-time visitors, with multiple diners reporting that a single seafood platter contained enough food to comfortably feed an entire family of six.

The kitchen operates on the principle that guests who leave hungry have been failed by the establishment, a standard that shapes every plate that exits the kitchen.

Even the salad bar, staffed by dedicated team members who assemble each plate to order in a format reminiscent of a well-run sandwich counter, reflects this commitment to generosity. Regulars advise communicating clearly about portion preferences at the salad station, as the default serving is famously abundant.

Entree portions are consistently described as large enough to guarantee satisfying leftovers for the following day, which is a practical benefit that elevates the overall value proposition of dining at this beloved Hortonville institution considerably.

A Menu Built Around Classic Midwestern Comfort Food

Beyond the prime rib that anchors its reputation, Black Otter Supper Club maintains a menu of impressive breadth that rewards exploration across multiple visits. The Friday night fish fry stands as a separate institution within the institution, drawing devoted crowds who arrive specifically for the crispy, properly prepared perch and whitefish that represent the best of Wisconsin fish fry tradition.

BBQ ribs, cajun broiled haddock, and an extensive seafood selection that includes lobster tails, scallops, and six distinct shrimp preparations round out a menu that refuses to be pigeonholed.

Clam chowder arrives thick with potato chunks and genuine flavor, while the hot bacon dressing available at the salad bar rewards the curious diner willing to ask for it specifically. The kitchen also offers a midweek smothered chicken special that has developed its own loyal following.

Every section of the menu reflects a culinary perspective grounded in honest ingredients, careful preparation, and a deep respect for the Midwestern appetite.
