Prime Rib and Western Curiosities at Ketchum’s Pio

A baked potato that occupies roughly half the plate sets the tone at Ketchum’s Pio. The Jim Spud arrives loaded and substantial enough to stand in as dinner, not merely a side waiting beside a steak.

This is Idaho comfort food in a full, cheerful saloon setting: prime rib, ribeyes, New York steaks, pork chops, shrimp and local fish, with a bar nearby and more things overhead and on the walls than most diners can take in during one meal.

The room is dim, busy and distinctly Western without posing as a hushed steakhouse. It works for a drink at the bar, a booth dinner with friends, a family meal or an anniversary table where the evening may stretch past the first round.

The Ketchum Cut prime rib is the order that keeps coming up. It is known for being tender, flavorful and generously sized, the sort of plate that suits an appetite built outdoors in the Sun Valley area.

There is also a Ketchum Cut served with grilled shrimp, a useful option for someone who wants the classic prime-rib dinner but would like a little surf alongside it. The menu’s approach is refreshingly direct: bring on the beef, make the portions count, and do not skimp on the potato.

Steak remains a broad category here rather than a single-house-special operation. A ribeye, New York steak, beef kabobs and steak medallions with shrimp give a group several routes through dinner, which is handy when one person is set on prime rib and another wants something a little different.

The massive loaded Jim Spud deserves its own bit of table space. Its size is part of the appeal, but so is the simple Idaho logic behind it: a baked potato can be a full meal when it is dressed properly and given enough room to be itself.

Meals may begin with sourdough bread and a large dinner salad with a mix of vegetables. Shrimp cocktail, served with a lemon wedge, is another familiar opening move before the bigger plates begin arriving.

Portions throughout the menu tend toward generous. That gives a meal a pleasantly old-school rhythm: bread and salad first, a substantial entrée next, and perhaps enough remaining appetite for dessert only if the table is sharing.

The menu is not limited to red meat. Halibut is among the seafood choices, and Idaho rainbow trout comes with drawn butter and lemon, a straightforward preparation that lets the fish stay central.

Grilled shrimp and fresh-water shrimp add more variety, while the steak-and-shrimp combinations make it easy to split the difference. Not every diner arrives looking for a giant steak, and the kitchen gives them plenty of company at the table.

That breadth also helps with mixed parties. One person can commit to a bone-in pork chop, another to trout, and someone else to a loaded potato with all the heft they need.

The Pio’s décor goes well beyond a few wagon-wheel gestures. The walls and ceiling are crowded with Western and rustic objects, including taxidermy and a full-sized canoe, so a diner has plenty to inspect between bites.

The visual collection gives the room a pleasantly cluttered, collected-over-time quality. A booth does not simply face a blank wall; it comes with its own field of curiosities, which helps keep a long dinner from feeling static.

The effect is cozy in one corner and more bustling in another. The place can be energetic, especially when the dining room and bar are both active, but conversation generally remains possible over the background noise.

The bar is not an afterthought here. Cocktails are well represented, pours are generous, and the wine list includes both by-the-glass choices and bottles. Arriving early enough for a drink before dinner gives the evening a natural opening chapter.

Seating includes bar seats, counter seats, booths and indoor tables, along with a private dining room. That mix keeps the restaurant from having one fixed personality: a couple can take a smaller table, while a group can settle into a more social arrangement.

There is also a large downstairs room within the venue, though its availability can vary. The main spaces already provide plenty of saloon character, from the bar crowd to the booth-filled dining areas.

Dessert can go in two very American directions: mud pie for a richer finish or mixed-berry cobbler for something fruitier. After a prime rib dinner and a plate-sized potato, sharing is not a bad strategy.

Still, this is a restaurant built around generous pleasures, and a proper dessert makes sense when the table is lingering over another coffee, a last cocktail or the final look around at the collection overhead.

The restaurant does not take reservations. During quieter periods, seating may be easy; busier seasons can bring a wait, and an early dinner—around 4:30 p.m., for example—can put you ahead of the crowd.

Free parking has been available in a lot and on the street. Once inside, expect a lively room rather than a silent one, with the bar, dining room and richly packed décor all contributing to the evening’s momentum.
